Introduction

1 shows a wireless device 100 having a communication module 110 coupled to a primary antenna 130 and a diversity antenna 140. The communication module 110 (and its constituent components) can be controlled by the controller 120. through The letter module 110 includes a transceiver 112 that is configured to convert between an analog radio frequency (RF) signal and a digital data signal. To this end, the transceiver 112 can include a digital analog converter, an analog digital converter, a local oscillator for modulating or demodulating a base frequency analog signal into a carrier frequency or self-carrier frequency modulation or demodulation of a fundamental frequency analog signal. A baseband processor, or other component, that converts between a digital sample and a data bit (eg, voice or other type of material).

The communication module 110 further includes an RF module 114 coupled between the primary antenna 130 and the transceiver 112. Since the RF module 114 can be physically close to the primary antenna 130 to reduce attenuation due to cable loss, the RF module 114 can be referred to as a front end module (FEM). The RF module 114 may perform processing on analog signals received from the primary antenna 130 for use at or from the transceiver 112 for transmission via the primary antenna 130. To this end, the RF module 114 can include filters, power amplifiers, band select switches, matching circuits, and other components. Similarly, the communication module 110 includes a diversity RF module 116 coupled between the diversity antenna 140 and the transceiver 112 for similar processing.

When a signal is transmitted to the wireless device, signals can be received at both the primary antenna 130 and the diversity antenna 140. The primary antenna 130 and the diversity antenna 140 may be physically spaced apart such that signals having different characteristics at the primary antenna 130 and the diversity antenna 140 are received. For example, in one embodiment, primary antenna 130 and diversity antenna 140 can receive signals having different attenuation, noise, frequency response, or phase shift. Transceiver 112 may use two signals having different characteristics to determine the data bits corresponding to the signal. In some implementations, the transceiver 112 selects between the primary antenna 130 and the diversity antenna 140 based on the characteristics, such as selecting an antenna having the highest signal to interference ratio. In some implementations, the transceiver 112 combines the signals from the primary antenna 130 and the diversity antenna 140 to increase the signal to noise ratio of the combined signal. In some implementations, the transceiver 112 processes the signals for multiple input/multiple output (MIMO) communications.

Since the diversity antenna 140 is physically spaced apart from the primary antenna 130, the diversity antenna 140 is coupled to the communication by a transmission line 135, such as a cable or printed circuit board (PCB) trace. Module 110. In some implementations, transmission line 135 is lossy and causes the signal received at diversity antenna 140 to decay before it reaches communication module 110. Thus, in some implementations, a gain is applied to the signal received at diversity antenna 140, as described below. Gain (and other analog processing, such as filtering) can be applied by the diversity receiver module. Since the diversity receiver module can be positioned to be physically close to the diversity antenna 140, it can be referred to as a diversity receiver front end module.

2 shows a diversity receiver (DRx) configuration 200 including a DRx front end module (FEM) 210. The DRx configuration 200 includes a diversity antenna 140 that is configured to receive a diversity signal and provide the diversity signal to the DRx FEM 210. The DRx FEM 210 is configured to perform processing on the diversity signals received by the self-diversity antenna 140. For example, DRx FEM 210 can be configured to filter the diversity signal to one or more active frequency bands, for example, as indicated by controller 120. As another example, the DRx FEM 210 can be configured to amplify the diversity signal. To this end, the DRx FEM 210 can include filters, low noise amplifiers, band select switches, matching circuits, and other components.

The DRx FEM 210 transmits the processed diversity signal to a downstream module, such as a diversity RF (D-RF) module 116, via a transmission line 135 that feeds another processed diversity signal to the transceiver 112. The diversity RF module 116 (and, in some implementations, the transceiver) is controlled by the controller 120. In some implementations, the controller 120 can be implemented within the transceiver 112.

3 shows that in some embodiments, a diversity receiver (DRx) configuration 300 can include a DRx module 310 having multiple paths corresponding to multiple frequency bands. The DRx configuration 300 includes a diversity antenna 140 that is configured to receive a diversity signal. In some implementations, the diversity signal can be a single band signal that includes data modulated to a single frequency band. In some implementations, the diversity signal can be a multi-frequency signal (also referred to as an inter-frequency carrier aggregation signal) that includes data modulated onto multiple frequency bands.

The DRx module 310 has an input from the diversity antenna 140 that receives the diversity signal and will be processed The diversity signal is provided to the output of transceiver 330 (via transmission line 135 and diversity RF module 320). The DRx module 310 inputs are fed into the input of the first multiplexer (MUX) 311. The first multiplexer 311 includes a plurality of multiplexer outputs, each of which corresponds to a path between the input and output of the DRx module 310. Each of the paths may correspond to a respective frequency band. The DRx module 310 output is provided by the output of the second multiplexer 312. The second multiplexer 312 includes a plurality of multiplexer inputs, each of which corresponds to one of the paths between the inputs and outputs of the DRx module 310.

The frequency band may be a cellular band such as the UMTS (Universal Mobile Telecommunications System) band. For example, the first frequency band may be a UMTS downlink connection or "Rx" band 2 between 1930 megahertz (MHZ) and 1990 MHz, and the second frequency band may be a UMTS downlink link between 869 MHz and 894 MHz or "Rx Band 5. Other downstream link bands may be used, such as those described below in Table 1 or other non-UMTS bands.

In some implementations, the DRx module 310 includes a DRx controller 302 that receives signals from a controller 120 (also referred to as a communication controller) and selectively enables input and output based on the received signals. One or more of the multiple paths. In some implementations, the DRx module 310 does not include the DRx controller 302, and the controller 120 selectively initiates one or more of the plurality of paths.

As noted herein, in some implementations, the diversity signal is a single band signal. Thus, in some implementations, the first multiplexer 311 is a single-pole/multi-throw (SPMT) switch that routes the diversity signal to a frequency band corresponding to a single-band signal in a plurality of paths based on signals received from the DRx controller 302. One. The DRx controller 302 can generate a signal based on the band selection signal received by the DRx controller 302 from the communication controller 120. Similarly, in some implementations, the second multiplexer 312 is an SPMT switch that routes signals from one of a plurality of paths corresponding to a frequency band of a single band signal based on a signal received from the DRx controller 302.

As noted herein, in some implementations, the diversity signal is a multi-band signal. Thus, in some implementations, the first multiplexer 311 is a signal splitter based on self-DRx control The splitter control signal received by the controller 302 routes the diversity signal to two or more paths in the plurality of paths corresponding to two or more frequency bands of the multi-band signal. The function of the signal splitter can be implemented as a SPMT switch, a duplexer filter, or some combination of these components. Similarly, in some implementations, the second multiplexer 312 is a signal combiner that combines two or more of the plurality of paths corresponding to the multi-band signals based on the combiner control signals received from the DRx controller 302. A signal of two or more paths of a frequency band. The function of the signal combiner can be implemented as a SPMT switch, a duplexer filter, or some combination of these components. The DRx controller 302 can generate a splitter control signal and a combiner control signal based on the band select signal received by the DRx controller 302 from the communication controller 120.

Accordingly, in some implementations, the DRx controller 302 is configured to selectively initiate one or more of a plurality of paths based on a band selection signal received by the DRx controller 302 (eg, from the communication controller 120). In some implementations, the DRx controller 302 is configured to selectively initiate one or more of a plurality of paths by transmitting a splitter control signal to the signal splitter and transmitting the combiner control signal to the signal combiner .

The DRx module 310 includes a plurality of band pass filters 313a through 313d. Each of the bandpass filters 313a through 313d is disposed along a corresponding one of the plurality of paths and configured to filter the signal received at the bandpass filter to a respective frequency band of one of the plurality of paths. In some implementations, the bandpass filters 313a through 313d are further configured to filter the signal received at the bandpass filter to a respective subband of the plurality of paths below the row concatenating subband. The DRx module 310 includes a plurality of amplifiers 314a through 314d. Each of the amplifiers 314a through 314d is disposed along a corresponding one of the plurality of paths and configured to amplify the signal received at the amplifier.

In some implementations, amplifiers 314a through 314d are narrowband amplifiers that are configured to amplify signals within respective frequency bands of the path in which the amplifiers are disposed. In some implementations, amplifiers 314a through 314d can be controlled by DRx controller 302. For example, in some implementations, each of the amplifiers 314a through 314d includes an enable/disable input and is based on receiving The amplifier enable signal and enable/disable input are enabled (or disabled). The amplifier enable signal can be transmitted by the DRx controller 302. Thus, in some implementations, the DRx controller 302 is configured to selectively transmit an amplifier enable signal to one or more of the amplifiers 314a through 314d disposed along one or more of the plurality of paths, respectively. Start one or more of the multiple paths. In such implementations, unlike being controlled by DRx controller 302, first multiplexer 311 can be a signal splitter that routes the diversity signal to each of a plurality of paths, and second multiplexer 312 can be A signal combiner that combines signals from each of a plurality of paths. However, in implementations where DRx controller 302 controls first multiplexer 311 and second multiplexer 312, DRx controller 302 may also enable (or disable) specific amplifiers 314a through 314d (for example) to conserve battery.

In some implementations, amplifiers 314a through 314d are variable gain amplifiers (VGAs). Thus, in some implementations, the DRx module 310 includes a plurality of variable gain amplifiers (VGAs), each of the VGAs being disposed along a corresponding one of the plurality of paths and configured to amplify reception at the VGA The VGA has a gain controlled by an amplifier control signal received from the DRx controller 302.

The gain of the VGA can be bypassable, variable step size, continuously variable. In some implementations, at least one of the VGAs includes a fixed gain amplifier and a bypass switch that can be controlled by the amplifier control signal. The bypass switch can (in the first position) turn off the line between the input of the fixed gain amplifier to the output of the fixed gain amplifier, thereby allowing the signal to bypass the fixed gain amplifier. The bypass switch can (in the second position) open the line between the input and the output to pass the signal through the fixed gain amplifier. In some implementations, the fixed gain amplifier is deactivated or otherwise reconfigured to accommodate the bypass mode when the bypass switch is in the first position.

In some implementations, at least one of the VGAs includes a variable step gain amplifier configured to amplify a signal received at the VGA, the VGA having one of a plurality of configured quantities indicated by an amplifier control signal Gain. In some implementations, at least VGA One includes a continuously variable gain amplifier configured to amplify a signal received at a VGA having a gain proportional to the amplifier control signal.

In some implementations, amplifiers 314a through 314d are variable current amplifiers (VCAs). The current drawn by the VCA can be bypassable, variable step size, continuously variable. In some implementations, at least one of the VCAs includes a fixed current amplifier and a bypass switch that can be controlled by the amplifier control signal. The bypass switch can (in the first position) turn off the line between the input of the fixed current amplifier and the output of the fixed current amplifier, thereby allowing the signal to bypass the fixed current amplifier. The bypass switch can (in the second position) open the line between the input and the output, thereby passing the signal through the fixed current amplifier. In some implementations, when the bypass switch is in the first position, the fixed current amplifier is deactivated or otherwise reconfigured to accommodate the bypass mode.

In some implementations, at least one of the VCAs includes a variable step current amplifier configured to capture one of a plurality of configured quantities indicated by the amplifier control signal Current to amplify the signal received at the VCA. In some implementations, at least one of the VCAs includes a continuously variable current amplifier configured to amplify a signal received at the VCCA by extracting a current proportional to the amplifier control signal.

In some implementations, amplifiers 314a through 314d are fixed gain, fixed current amplifiers. In some implementations, amplifiers 314a through 314d are fixed gain, variable current amplifiers. In some implementations, amplifiers 314a through 314d are variable gain, fixed current amplifiers. In some implementations, amplifiers 314a through 314d are variable gain, variable current amplifiers.

In some implementations, the DRx controller 302 generates an amplifier control signal based on a quality of service metric of the input signal received at the input. In some implementations, the DRx controller 302 generates an amplifier control signal based on signals received from the communication controller 120, which in turn can be based on a quality of service (Qos) metric of the received signal. QoS of received signals The metric may be based at least in part on a diversity signal received on diversity antenna 140 (eg, an input signal received at the input). The QoS metric of the received signal can be further based on the signal received on the primary antenna. In some implementations, the DRx controller 302 generates an amplifier control signal based on the QoS metric of the diversity signal without receiving a signal from the communication controller 120.

In some implementations, the QoS metric includes signal strength. As another example, the QoS metrics may include a bit error rate, a data throughput, a transmission delay, or any other QoS metric.

As indicated herein, the DRx module 310 has an input that receives the diversity signal from the diversity antenna 140 and an output that provides the processed diversity signal to the transceiver 330 (via the transmission line 135 and the diversity RF module 320). The diversity RF module 320 receives the processed diversity signals via transmission line 135 and performs further processing. In particular, the processed diversity signal is separated or routed by the diversity RF multiplexer 321 to one or more paths on which the separated or routed signals are filtered by the corresponding bandpass filters 323a through 323d and corresponding The amplifiers 324a to 324d are amplified. The output of each of the amplifiers 324a through 324d is provided to the transceiver 330.

The diversity RF multiplexer 321 can be controlled by the controller 120 (either directly or via a on-wafer diversity RF controller) to selectively initiate one or more of the paths. Similarly, amplifiers 324a through 324d can be controlled by controller 120. For example, in some implementations, each of amplifiers 324a through 324d includes an enable/disable input and is enabled (or disabled) based on an amplifier enable signal. In some implementations, amplifiers 324a through 324d are variable gain amplifiers (VGAs) that amplify signals received at the VGA having on-wafer diversity RF controllers controlled by controller 120 (or by controller 120) The gain of the received amplifier control signal control. In some implementations, amplifiers 324a through 324d are variable current amplifiers (VCAs).

In the case where the DRx module 310 added to the receiver chain already includes the diversity RF module 320, the number of bandpass filters in the DRx configuration 300 is doubled. Thus, in some implementations, bandpass filters 323a through 323d are not included in diversity RF module 320. Specifically, the band pass filters 313a through 313d of the DRx module 310 are used to reduce the strength of the out-of-band locker. In addition, the automatic gain control (AGC) table of the diversity RF module 320 can be shifted to enable The amount of gain provided by amplifiers 324a through 324d of diversity RF module 320 reduces the amount of gain provided by amplifiers 314a through 314d of DRx module 310.

For example, if the DRx module gain is 15 dB and the receiver sensitivity is -100 dBm, the diversity RF module 320 will achieve a sensitivity of -85 dBm. If the closed loop AGC of the diversity RF module 320 is active, its gain will automatically drop by 15 dB. However, both the signal component and the out-of-band locker are amplified by 15 dB. Therefore, the 15 dB gain reduction of the diversity RF module 320 can also be accompanied by an increase of 15 dB in its linearity. In particular, the amplifiers 324a through 324d of the diversity RF module 320 can be designed such that the linearity of the amplifier increases with decreasing gain (or increased current).

In some implementations, controller 120 controls the gain (and/or current) of amplifiers 314a through 314d of DRx module 310 and amplifiers 324a through 324d of diversity RF module 320. As in the example herein, in response to increasing the amount of gain provided by amplifiers 314a through 314d of DRx module 310, controller 120 may reduce the amount of gain provided by amplifiers 324a through 324d of diversity RF module 320. Thus, in some implementations, controller 120 is configured to generate downstream amplifier control signals (amplifiers 324a through 324d for diversity RF module 320) based on amplifier control signals (amplifiers 314a through 314d for DRx module 310). The gain of one or more downstream amplifiers 324a through 324d coupled to the output of (of the DRx module 310) is controlled via transmission line 135. In some implementations, controller 120 also controls the gain of other components of the wireless device, such as an amplifier in a front end module (FEM), based on the amplifier control signals.

As noted herein, in some implementations, band pass filters 323a through 323d are not included. Thus, in some implementations, at least one of the downstream amplifiers 324a through 324d is coupled to the output (of the DRx module 310) via the transmission line 135 without passing through a downstream bandpass filter.

4 shows that in some embodiments, the diversity receiver configuration 400 can include a diversity RF module 420 having fewer amplifiers than the diversity receiver (DRx) module 310. The diversity receiver configuration 400 includes a diversity antenna 140 and a DRX module 310 as described herein with respect to FIG. The output of the DRx module 310 is passed via a transmission line 135 to a diversity RF module 420 that is different from the diversity RF module 320 of FIG. 3, except that the diversity RF module 420 of FIG. 4 includes fewer amplifiers than the DRx module 310.

As mentioned herein, in some implementations, the diversity RF module 420 does not include a band pass filter. Thus, in some implementations, one or more of the diversity RF modules 420 424 need not be band specific. In particular, the diversity RF module 420 can include one or more paths that are not mapped one-to-one with the path of the DRx module 310, each path including an amplifier 424. This mapping of paths (or corresponding amplifiers) can be stored in controller 120.

Thus, although the DRx module 310 includes several paths each corresponding to a frequency band, the diversity RF module 420 can include one or more paths that do not correspond to a single frequency band.

In some implementations (as shown in FIG. 4), the diversity RF module 420 includes a single wideband or tunable amplifier 424 that amplifies the signal received from the transmission line 135 and outputs the amplified signal to the multiplexer 421. The multiplexer 421 includes a plurality of multiplexer outputs, each of which corresponds to a respective frequency band. In some implementations, the diversity RF module 420 does not include any amplifiers.

In some implementations, the diversity signal is a single band signal. Thus, in some implementations, multiplexer 421 is an SPMT switch that routes a diversity signal based on a signal received from controller 120 to one of a plurality of outputs corresponding to a frequency band of a single frequency signal. In some implementations, the diversity signal is a multi-band signal. Thus, in some implementations, multiplexer 421 is a signal splitter that routes the diversity signal based on a splitter control signal received from controller 120 to two or more frequency bands corresponding to the multi-frequency signal in the plurality of outputs Two or more outputs. In some implementations, the diversity RF module 420 can be combined with the transceiver 330 into a single module.

In some implementations, the diversity RF module 420 includes a plurality of amplifiers, each of which corresponds to a set of frequency bands. The signal from transmission line 135 can be fed into a band splitter that outputs a higher frequency to the high frequency amplifier along the first path and a lower frequency to the low frequency amplifier along the second path. The output of each of the amplifiers can be provided to be configured to The signal is routed to the corresponding input multiplexer 421 of the transceiver 330.

FIG. 5 shows that in some embodiments, the diversity receiver configuration 500 can include a DRx module 510 coupled to the shutdown module filter 513. The DRx module 510 can include a package substrate 501 configured to receive a plurality of components and a receiving system implemented on the package substrate 501. The DRx module 510 can include one or more signal paths that are routed away from the DRx module 510 and provided to a system integrator, designer, or manufacturer to support filters for any desired frequency band.

The DRx module 510 includes a number of paths between the inputs and outputs of the DRx module 510. The DRx module 510 includes a bypass path initiated between the input and output by a bypass switch 519 controlled by the DRx controller 502. Although FIG. 5 illustrates a single bypass switch 519, in some implementations, the bypass switch 519 can include a plurality of switches (eg, a first switch that is disposed proximate to the input entity and a second switch that is proximate to the output via the placement entity). As shown in Figure 5, the bypass path does not include a filter or amplifier.

The DRx module 510 includes a plurality of multiplexer paths including a first multiplexer 511 and a second multiplexer 512. The multiplexer path includes a plurality of open module paths, and the open multiplexer 511 includes a first multiplexer 511, band pass filters 313a to 313d implemented on the package substrate 501, and an amplifier 314a implemented on the package substrate 501. Up to 314d and second multiplexer 512. The multiplexer path includes one or more shutdown module paths including a first multiplexer 511, a bandpass filter 513 that is implemented to exit the package substrate 501, an amplifier 514, and a second multiplexer 512. The amplifier 514 can be a wideband amplifier implemented on the package substrate 501 or can be implemented outside the package substrate 501. As described herein, amplifiers 314a through 314d, 514 can be variable gain amplifiers and/or variable current amplifiers.

The DRx controller 502 is configured to selectively initiate one or more of a plurality of paths between the input and the output. In some implementations, the DRx controller 502 is configured to selectively initiate one or more of the plurality of paths based on a band selection signal received by the DRx controller 502 (eg, from the communication controller). The DRx controller 502 can be opened or closed by, for example, Bypass switch 519, enables or disables amplifiers 314a through 314d, 514, controls multiplexers 511, 512, or selectively initiates paths via other mechanisms. For example, the DRx controller 502 can set the gain along the path (eg, the path between the filters 313a through 313d, 513 and the amplifiers 314a through 314d, 514) or by setting the gains of the amplifiers 314a through 314d, 514 to substantially zero. To open or close the switch.

Example A: Variable Gain Amplifier

As described herein, the amplifier used to process the received signal can be a variable gain amplifier (VGA). Thus, in some implementations, the DRx module can include a plurality of variable gain amplifiers (VGAs), wherein each of the VGAs is disposed along a corresponding one of the plurality of paths and configured to amplify signals received at the VGA The VGA has a gain controlled by an amplifier control signal received from the DRx controller.

In some embodiments, the gain of the VGA can be bypassable, variable step size, continuously variable. FIG. 6 shows that in some embodiments, the variable gain amplifier A350 can be bypassable. The VGA A350 includes a fixed gain amplifier A351 and a bypass switch A352 that can be controlled by an amplifier control signal generated by the DRx controller A302. The bypass switch A352 can (in the first position) turn off the line from the input of the fixed gain amplifier A351 to the output of the fixed gain amplifier, thereby allowing the signal to bypass the fixed gain amplifier A351. The bypass switch A352 can (in the second position) open the line between the input of the fixed gain amplifier A351 and the output of the fixed gain amplifier A351, thereby passing the signal through the fixed gain amplifier A351. In some implementations, the fixed gain amplifier is deactivated or otherwise reconfigured to accommodate the bypass mode when the bypass switch is in the first position. Referring to the example of FIG. 3, in some implementations, at least one of VGAs 314a through 314d can include a fixed gain amplifier and a bypass switch that can be controlled by an amplifier control signal.

FIG. 7 shows that in some embodiments, the gain of variable gain amplifier A360 can be variable step size or continuously variable. In some implementations, VGA A360 is variable step size and is amplified in VGA in response to a digital amplifier control signal generated by DRx controller A302. The signal received at the input of the A360, the VGA A360 has a gain of one of a plurality of configured quantities indicated by the digital signal. In some implementations, VGA A360 is continuously variable and amplifies the signal received at the input of VGA A360 in response to an analog amplifier control signal generated by DRx controller A302, which has characteristics similar to analog signals (eg, Voltage or duty cycle) proportional gain. Referring to the example of FIG. 3, in some implementations, at least one of the VGAs 314a through 314d can include a variable step gain amplifier configured to amplify a signal received at the VGA, the VGA A gain having one of a plurality of configured quantities indicated by an amplifier control signal. In some implementations, at least one of the VGAs 314a through 314d of FIG. 3 can include a continuously variable gain amplifier configured to amplify a signal received at the VGA with an amplifier control signal Proportional gain.

In some implementations, amplifiers 314a through 314d of FIG. 3 can be variable current amplifiers (VCAs). The current drawn by the VCA can be bypassable, variable step size, continuously variable. In some implementations, at least one of the VCAs includes a fixed current amplifier and a bypass switch that can be controlled by the amplifier control signal. The bypass switch can (in the first position) turn off the line between the input of the fixed current amplifier and the output of the fixed current amplifier, thereby allowing the signal to bypass the fixed current amplifier. The bypass switch can (in the second position) open the line between the input and the output, thereby passing the signal through the fixed current amplifier. In some implementations, when the bypass switch is in the first position, the fixed current amplifier is deactivated or otherwise reconfigured to accommodate the bypass mode.

In some implementations, at least one of the VCAs includes a variable step current amplifier configured to capture one of a plurality of configured quantities indicated by the amplifier control signal Current to amplify the signal received at the VCA. In some implementations, at least one of the VCAs includes a continuously variable current amplifier configured to amplify a signal received at the VCA by extracting a current proportional to the amplifier control signal.

In some implementations, the amplifiers 314a through 314d of Figure 3 can be fixed gain, fixed current amplifiers. In some implementations, amplifiers 314a through 314d are fixed gain, variable current amplifiers. In some implementations, amplifiers 314a through 314d are variable gain, fixed current amplifiers. In some implementations, amplifiers 314a through 314d are variable gain, variable current amplifiers.

In some implementations, the DRx controller 302 generates an amplifier control signal based on a quality of service metric of the input signal received at the input of the first multiplexer 311. In some implementations, the DRx controller 302 generates an amplifier control signal based on signals received from the communication controller 120, which in turn can be based on a quality of service (Qos) metric of the received signal. The QoS metric of the received signal can be based at least in part on the diversity signal received on the diversity antenna 140 (eg, the input signal received at the input). The QoS metric of the received signal can be further based on the signal received on the primary antenna. In some implementations, the DRx controller 302 generates an amplifier control signal based on the QoS metric of the diversity signal without receiving a signal from the communication controller 120.

In some implementations, the QoS metric includes signal strength. As another example, the QoS metrics may include a bit error rate, a data throughput, a transmission delay, or any other QoS metric.

As noted herein, the DRx module 310 of FIG. 3 can have an input that receives the diversity signal from the diversity antenna 140 and an output that provides the processed diversity signal to the transceiver 330 (via the transmission line 135 and the diversity RF module 320). The diversity RF module 320 receives the processed diversity signals via transmission line 135 and performs further processing. In particular, the processed diversity signal is separated or routed by the diversity RF multiplexer 321 to one or more paths on which the separated or routed signals are filtered by the corresponding bandpass filters 323a through 323d and corresponding The amplifiers 324a to 324d are amplified. The output of each of the amplifiers 324a through 324d is provided to the transceiver 330.

The diversity RF multiplexer 321 can be controlled by the controller 120 (either directly or via a on-wafer diversity RF controller) to selectively initiate one or more of the paths. Similarly, amplifier 324a Up to 324d can be controlled by controller 120. For example, in some implementations, each of amplifiers 324a through 324d includes an enable/disable input and is enabled (or disabled) based on an amplifier enable signal. In some implementations, amplifiers 324a through 324d are variable gain amplifiers (VGAs) that amplify signals received at the VGA having on-wafer diversity RF controllers controlled by controller 120 (or by controller 120) The gain of the received amplifier control signal control. In some implementations, amplifiers 324a through 324d are variable current amplifiers (VCAs).

In the case where the DRx module 310 added to the receiver chain already includes the diversity RF module 320, the number of bandpass filters in the DRx configuration 300 is doubled. Thus, in some implementations, bandpass filters 323a through 323d are not included in diversity RF module 320. Specifically, the band pass filters 313a through 313d of the DRx module 310 are used to reduce the strength of the out-of-band locker. In addition, the automatic gain control (AGC) table of the diversity RF module 320 can be shifted to reduce the amount of gain provided by the amplifiers 324a through 324d of the diversity RF module 320 by the gains provided by the amplifiers 314a through 314d of the DRx module 310. the amount.

For example, if the DRx module gain is 15 dB and the receiver sensitivity is -100 dBm, the diversity RF module 320 will achieve a sensitivity of -85 dBm. If the closed loop AGC of the diversity RF module 320 is active, its gain will automatically drop by 15 dB. However, both the signal component and the out-of-band locker are amplified by 15 dB. Thus, in some implementations, the 15 dB gain reduction of the diversity RF module 320 is accompanied by a 15 dB increase in its linearity. In particular, the amplifiers 324a through 324d of the diversity RF module 320 can be designed such that the linearity of the amplifier increases with decreasing gain (or increased current).

In some implementations, controller 120 controls the gain (and/or current) of amplifiers 314a through 314d of DRx module 310 and amplifiers 324a through 324d of diversity RF module 320. As in the example herein, in response to increasing the amount of gain provided by amplifiers 314a through 314d of DRx module 310, controller 120 may reduce the amount of gain provided by amplifiers 324a through 324d of diversity RF module 320. Thus, in some implementations, controller 120 is configured to generate downstream amplifier control based on amplifier control signals (amplifiers 314a through 314d for DRx module 310) Signals (for amplifiers 324a through 324d of diversity RF module 320) are used to control the gain of one or more downstream amplifiers 324a through 324d coupled to the output of (of DRx module 310) via transmission line 135. In some implementations, controller 120 also controls the gain of other components of the wireless device, such as an amplifier in a front end module (FEM), based on the amplifier control signals.

As noted herein, in some implementations, band pass filters 323a through 323d are not included. Thus, in some implementations, at least one of the downstream amplifiers 324a through 324d is coupled to the output (of the DRx module 310) via the transmission line 135 without passing through a downstream bandpass filter. Examples of such implementations are described herein with reference to FIG.

FIG. 8 shows that in some embodiments, the diversity receiver configuration A600 can include a DRx module A 610 with tunable matching circuitry. In particular, the DRx module A 610 can include one or more tunable matching circuits disposed at one or more of the inputs and outputs of the DRx module A 610.

It is unlikely that multiple frequency bands received on the same diversity antenna 140 will achieve an ideal impedance match. To match each frequency band using a compact matching circuit, tunable input matching circuit A 616 can be implemented at the input of DRx module A 610 and controlled by DRx controller A 602 (eg, based on a band selection signal from the communication controller). The DRx controller A 602 can tune the tunable input matching circuit A 616 based on a lookup table that associates the frequency band (or set of frequency bands) with the tuning parameters. The tunable input matching circuit A616 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit. In particular, tunable input matching circuit A 616 can include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the input of the DRx module A 610 and the input of the first multiplexer A 311 or can be connected between the input of the DRx module A 610 and the ground voltage.

Similarly, where only one transmission line 135 (or at least few cables) carries signals for many frequency bands, it is not possible for multiple frequency bands to achieve ideal impedance matching. To match each frequency band with a compact matching circuit, the tunable output matching circuit A617 can be used in the DRx module. The output of A610 is implemented and controlled by DRx controller A 602 (e.g., based on a band selection signal from a communications controller). The DRx controller A 602 can tune the tunable output matching circuit A 618 based on a lookup table that associates the frequency band (or set of frequency bands) with the tuning parameters. The tunable output matching circuit A617 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit. In particular, the tunable output matching circuit A617 can include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the output of the DRx module A 610 and the output of the second multiplexer A 312 or can be connected between the output of the DRx module A 610 and the ground voltage.

FIG. 9 shows that in some embodiments, the diversity receiver configuration A700 can include multiple antennas. Although FIG. 9 illustrates an embodiment having two antennas A740a through A740b and one transmission line 135, the aspects described herein may be implemented in embodiments having more than two antennas and/or two or more cables. .

The diversity receiver configuration A700 includes a DRx module A710 coupled to a first antenna A 740a and a second antenna A 740b. In some implementations, the first antenna A 740a is a high band antenna configured to receive signals transmitted at a higher frequency band, and the second antenna A 740b is configured to receive transmissions at a lower frequency band The low-band antenna of the signal.

The DRx module A710 includes a first tunable input matching circuit A716a at a first input of the DRx module A710 and a second tunable input matching circuit A716b at a second input of the DRx module A710. The DRx module A710 further includes a tunable output matching circuit A717 at the output of the DRx module A710. The DRx controller A 702 can tune each of the tunable matching circuits A716a through A716b, A717 based on a lookup table that associates the frequency bands (the set of frequency bands) with the tuning parameters. Each of the tunable matching circuits A716a through A716b, A717 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit.

The DRx module A710 includes an input of the DRx module A710 (coupled to a first input of the first antenna A740a and a second input coupled to the second antenna A740b) and an output (coupled to the transmission) Several paths between line 135).

The DRx controller A 702 can selectively initiate the path by, for example, enabling or disabling the amplifiers A714a through A714h, controlling the multiplexers A 711a through A 711b, A 712, or via other mechanisms as described herein.

Figure 10 shows an embodiment of a flow chart representation of a method of processing an RF signal. In some implementations (and as detailed below), method A800 is performed by a controller, such as DRx controller 302 of FIG. 3 or communication controller 120 of FIG. In some implementations, method A800 is performed by processing logic including hardware, firmware, software, or a combination thereof. In some implementations, method A800 executes code execution by a processor stored in a non-transitory computer readable medium (eg, memory). Briefly, method A800 includes receiving a band selection signal and following one or more The gain control paths route the received RF signals to process the received RF signals.

Method A800 begins at block A 810 with a controller receiving a band select signal. The controller may receive the band selection signal from another controller or may receive a band selection signal from a cellular base station or other external source. The band selection signal may indicate one or more frequency bands over which the wireless device will transmit and receive the RF signal. In some implementations, the band selection signal indicates a group band for carrier set communication.

In some implementations, the controller tunes one or more tunable matching circuits based on the received band selection signal. For example, the controller can tune the tunable matching circuit based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters.

At block A820, the controller selectively activates one or more paths of the diversity receiver (DRx) module based on the band selection signal. As described herein, a DRx module can include one or more inputs (coupled to one or more antennas) of the DRx module and one or more outputs (coupled to one or more cables) Several paths. The path can include a bypass path and a multiplexer path. The multiplexer path can include opening the module path and closing the module path.

The controller can control one or more by, for example, opening or closing one or more bypass switches, enabling or disabling the amplifier disposed along the path via the amplifier enable signal, via the splitter control signal, and/or the combiner control signal Multiple multiplexers or selectively initiate one or more of a plurality of paths via other mechanisms. For example, the controller can turn the switch placed along the path on or off or turn it on or off by setting the gain of the amplifier placed along the path to substantially zero.

At block A830, the controller sends an amplifier control signal to one or more amplifiers disposed along one or more of the initiated paths, respectively. The amplifier control signal controls the gain (or current) of the amplifier to which it is sent. In one embodiment, the amplifier includes a fixed gain amplifier and a bypass switch that can be controlled by the amplifier control signal. Thus, in one embodiment, the amplifier control signal indicates whether the bypass switch will be open or closed.

Thus, in one embodiment, the amplifier control signal indicates one of a plurality of configured quantities.

In one embodiment, the amplifier includes a continuously variable gain amplifier configured to amplify a signal received at the amplifier having a gain proportional to the amplifier control signal. Thus, in one embodiment, the amplifier control signal indicates a proportional amount of gain.

In some implementations, the controller generates one or more amplifier control signals based on quality of service (QoS) metrics of the input signals received at the input. In some implementations, the controller generates an amplifier control signal based on signals received from another controller, which in turn can be based on a QoS metric of the received signal. The QoS metric of the received signal can be based, at least in part, on the diversity signal received on the diversity antenna (eg, the input signal received at the input). The QoS metric of the received signal can be further based on the signal received on the primary antenna. In some implementations, the controller generates an amplifier control signal based on the QoS metric of the diversity signal without receiving a signal from another controller. For example, the QoS metric can include signal strength. As another example, the QoS metrics may include a bit error rate, a data throughput, a transmission delay, or any other QoS metric.

In some implementations, in block A830, the controller also transmits a downstream amplifier control signal based on the amplifier control signal to control the gain coupled to one or more downstream amplifiers via the one or more cables.

Example B: Phase shift component

11 shows that in some embodiments, the diversity receiver configuration B600 can include a DRx module B 610 having one or more phase matching components B624a through B624b. The DRx module B610 includes two paths: an input from the DRx module B610, coupled to the antenna 140, and an output from the DRx module B610 coupled to the transmission line 135.

In the DRx module B610 of FIG. 11, the signal separator and the band pass filter are implemented as a duplexer B611. The duplexer B611 includes an input coupled to the antenna 140, a first output coupled to the first amplifier 314a, and a second output coupled to the second amplifier 314b. At the first output, duplexer B 611 outputs a signal that is filtered at the input (eg, from antenna 140) to the first frequency band. At the second output, duplexer B 611 outputs a signal that is received at the input and filtered to the second frequency band. In some implementations, the duplexer B 611 can be replaced with a triplexer, quadruplexer, or any other multiplexer configured to separate the input signal received at the input of the DRx module B 610 into Propagation along multiple paths under multiple frequency bands Multiple signals.

As described herein, each of the amplifiers 314a through 314b is disposed along a corresponding one of the paths and configured to amplify a signal received at the amplifier. The outputs of amplifiers 314a through 314b are fed via corresponding phase shifting components B624a through B624b prior to being combined by signal combiner B612.

The signal combiner B612 includes a first input coupled to the first phase shifting component B 624a, a second input coupled to the second phase shifting component B 624b, and an output coupled to the output of the DRx module B 610. The signal at the output of the signal combiner is the sum of the signals at the first input and the second input. Thus, the signal combiner is configured to combine signals propagating along a plurality of paths.

When a signal is received by antenna 140, the signal is filtered by duplexer B611 to a first frequency band and propagates along a first path via first amplifier 314a. The filtered and amplified signal is phase shifted by first phase shifting component B 624a and fed to a first input of signal combiner B 612. In some implementations, the signal combiner B 612 or the second amplifier 314b does not prevent the signal from continuing to pass the signal combiner B 612 in the reverse direction along the second path. Thus, the signal propagates via the second phase shifting component B 624b and via the second amplifier 314b, wherein the signal is reflected off of the duplexer B 611. The reflected signal propagates through the second amplifier 314b and the second phase shifting component B 624b to reach the second input of the signal combiner B 612.

When the initial signal (at the first input of signal combiner B612) is out of phase with the reflected signal (at the second input of signal combiner B612), the summation performed by signal combiner B612 results in an output at signal combiner B612. The signal is weakened. Similarly, when the initial signal is in phase with the reflected signal, the summation performed by signal combiner B 612 results in signal enhancement at the output of signal combiner B 612. Thus, in some implementations, the second phase shifting component B 624b is configured to phase shift the signal (at least in the first frequency band) such that the initial signal is at least partially in phase with the reflected signal. In particular, the second phase shifting component B 624b is configured to phase shift the signal (at least in the first frequency band) such that the sum of the initial signal and the reflected signal The amplitude is greater than the amplitude of the initial signal.

For example, the second phase shifting component B 624b can be configured to phase shift the signal through the second phase shifting component B 624b by back propagation through the second amplifier 314b, reflection from the duplexer B 611, and via The forward shift introduced by the second amplifier 314b is -1/2 times the phase shift introduced. As another example, the second phase shifting component B 624b can be configured to phase shift the signal through the second phase shifting component B 624b by 360 degrees with reflection from the duplexer B611 by backpropagation via the second amplifier 314b. And one-half of the difference between the phase shifts introduced by forward propagation of the second amplifier 314b. In general, the second phase shifting component B 624b can be configured to phase shift the signal through the second phase shifting component B 624b such that the initial and reflected signals have a phase difference of integer multiples (including zero) of 360 degrees. .

As an example, the initial signal can be at 0 degrees (or any other reference phase) and can be introduced 140 degrees via the backpropagation of the second amplifier 314b, the reflection away from the duplexer B611, and the forward propagation via the second amplifier 314b. Phase shift. Thus, in some implementations, the second phase shifting component B 624b is configured to phase shift the signal through the second phase shifting component B 624b by -70 degrees. Therefore, the initial signal is phase-shifted to -70 degrees by the second phase shifting component B624b, by back propagation through the second amplifier 314b, reflection from the duplexer B611, and forward propagation via the second amplifier 314b. The phase shifts to 70 degrees and is phase shifted back to 0 degrees by the second phase shifting component B 624b.

In some implementations, the second phase shifting component B 624b is configured to phase shift the signal through the second phase shifting component B 624b by 110 degrees. Therefore, the initial signal is phase shifted to 110 degrees by the second phase shifting component B624b, by the back propagation through the second amplifier 314b, the reflection from the duplexer B611, and the forward phase propagation via the second amplifier 314b. Moves to 250 degrees and is phase shifted to 360 degrees by the second phase shifting component B 624b.

At the same time, the signal received by antenna 140 is filtered by duplexer B611 to the second frequency band and propagates along the second path via second amplifier 314b. The filtered and amplified signal is phase shifted by second phase shifting component B 624b and fed to a second input of signal combiner B 612. In a In some implementations, signal combiner B 612 or first amplifier 314a does not prevent the signal from continuing to pass signal combiner B 612 in the reverse direction along the first path. Thus, the signal propagates through the first phase shifting component B 624a and via the second amplifier 314a, where the signal is reflected off of the duplexer B 611. The reflected signal propagates through first amplifier 314a and first phase shifting component B 624a to reach a first input of signal combiner B 612.

When the initial signal (at the second input of signal combiner B612) is out of phase with the reflected signal (at the first input of signal combiner B612), the summation performed by signal combiner B612 results in an output at signal combiner B612 The signal at the location is weakened, and when the initial signal is in phase with the reflected signal, the summation performed by signal combiner B 612 causes the signal at the output of signal combiner B 612 to be boosted. Thus, in some implementations, the first phase shifting component B 624a is configured to phase shift the signal (at least in the second frequency band) such that the initial signal is at least partially in phase with the reflected signal.

For example, the first phase shifting component B 624a can be configured to phase shift the signal through the first phase shifting component B 624a by back propagation via the first amplifier 314a, reflection from the duplexer B 611, and through The forward shift of an amplifier 314a introduces a phase shift of -1/2 times. As another example, the first phase shifting component B 624a can be configured to phase shift the signal through the first phase shifting component B 624a by 360 degrees and by the backpropagation via the first amplifier 314a, leaving the duplexer B611 The reflection and the difference between the phase shifts introduced by the forward propagation of the first amplifier 314a are one-half. In general, the first phase shifting component B 624a can be configured to phase shift the signal through the first phase shifting component B 624a such that the initial signal and the reflected signal have a phase difference of an integer multiple (including zero) of 360 degrees. .

Phase shifting components B624a through B624b can be implemented as passive circuits. In particular, phase shifting components B624a through B624b can be implemented as LC circuits and include one or more passive components, such as inductors and/or capacitors. The passive components may be connected in parallel and/or in series and may be connected between the outputs of the amplifiers 314a through 314b and the inputs of the signal combiner B 612 or may be connected between the outputs of the amplifiers 314a through 314b and the ground voltage. In some implementations, the phase The shifting components B624a through B624b are integrated into the same wafer as the amplifiers 314a through 314b or integrated on the same package.

In some implementations (e.g., as shown in FIG. 11), phase shifting components B624a through B624b are disposed along the path after amplifiers 314a through 314b. Therefore, any signal attenuation produced by phase shifting components B624a through B624b does not affect the performance of module B 610, such as the signal to noise ratio of the output signal. However, in some implementations, phase shifting components B624a through B624b are disposed along the path before amplifiers 314a through 314b. For example, phase shifting components B624a through B624b can be integrated into an impedance matching component disposed between duplexer B611 and amplifiers 314a through 314b.

12 shows that in some embodiments, the diversity receiver configuration B 640 can include a DRx module B 641 having one or more phase matching components B 624a through B 624b and dual stage amplifiers B 614a through B 614b. The DRx module B641 of FIG. 12 is substantially similar to the DRx module B610 of FIG. 11 except that the two-stage amplifiers B614a to B614b in the DRx module B641 of FIG. 12 are substituted for the DRx module B610 of FIG. Amplifiers 314a through 314b.

13 shows that in some embodiments, the diversity receiver configuration B 680 can include a DRx module B 681 having one or more phase matching components B 624a through B 624b and a post combiner amplifier B 615. The DRx module B681 of FIG. 13 is substantially similar to the DRx module B610 of FIG. 11, except that the DRx module B681 of FIG. 13 includes a signal disposed between the output of the signal combiner B612 and the output of the DRx module B681. Rear combiner amplifier B615. Like amplifiers 314a through 314b, post-combination amplifier B 615 can be a variable gain amplifier (VGA) and/or a variable current amplifier controlled by a DRx controller (not shown).

14 shows that in some embodiments, the diversity receiver configuration B700 can include a DRx module B 710 having tunable phase shifting components B724a through B724d. Each of the tunable phase shifting components B724a through B724d can be configured to phase shift the signal through the tunable phase shifting component by an amount controlled by the phase shifted tuning signal received from the DRx controller B702.

The diversity receiver configuration B700 includes an input coupled to the antenna 140 and coupled The DRx module B710 to the output of the transmission line 135. The DRx module B710 includes several paths between the input and output of the DRx module B 710. In some implementations, DRx module B 710 includes one or more bypass paths (not shown) between the inputs and outputs initiated by one or more bypass switches controlled by DRx controller B 702.

The DRx module B710 includes a plurality of multiplexer paths including an input multiplexer B311 and an output multiplexer B312. The multiplexer path includes a plurality of open module paths (shown in the figure), and the open module paths include an input multiplexer B311, band pass filters B313a to B313d, amplifiers B314a to B314d, and tunable phase shifting component B724a to B724d, output multiplexer B312 and post combiner amplifier B615. The multiplexer path can include one or more shutdown module paths (not shown) as described herein. As also described herein, amplifiers B314a through B314d (including post gain amplifier B 615) can be variable gain amplifiers and/or variable current amplifiers.

The tunable phase shifting components B724a through B724d can include one or more variable components, such as inductors and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the outputs of amplifiers B314a through B314d and the input of output multiplexer B312, or can be connected between the outputs of amplifiers B314a through B314d and the ground voltage.

The DRx controller B702 is configured to selectively initiate one or more of a plurality of paths between the input and the output. In some implementations, DRx controller B 702 is configured to selectively initiate one or more of a plurality of paths based on a band selection signal received by DRx controller B 702 (eg, from a communication controller). The DRx controller B702 can selectively initiate the path by, for example, enabling or disabling the amplifiers B314a through B314d, controlling the multiplexers B311, B312, or via other mechanisms as described herein.

In some implementations, the DRx controller B702 is configured to tune the tunable phase shifting components B724a through B724d. In some implementations, the DRx controller B 702 can tune the tunable phase shifting components B 724a through B 724d based on the band selection signals. For example, the DRx controller B 702 can be based on a frequency band (or set of frequency bands) that is indicated by the band selection signal. A lookup table associated with the tuning parameters is used to tune the tunable phase shifting components B724a through B724d. Thus, in response to the band select signal, DRx controller B 702 can transmit a phase shifted tuning signal to tunable phase shifting components B724a through B724d of each active path to tunable phase shifting components (or variable thereof) based on tuning parameters Component) to tune.

The DRx controller B702 can be configured to tune the tunable phase shifting components B724a through B724d such that the out-of-band reflected signal is in phase with the out-of-band initial signal at the output multiplexer B312. For example, if the band selection signal indicates a first path corresponding to the first frequency band (via the first amplifier B314a), a second path corresponding to the second frequency band (via the second amplifier B314b), and a third path (via the third The amplifier B314c) will start, and the DRx controller B702 can tune the first tunable phase shifting component B724a such that (1) for the signal propagating along the second path (at the second frequency band), the initial signal and the edge a path backpropagating, a reflected signal leaving the bandpass filter B313a and propagating forward via the first path in phase; and (2) an initial signal for a signal propagating along the third path (at the third frequency band) The reflected signals propagating back along the first path, reflected off the bandpass filter B313a and propagating forward via the first path are in phase.

The DRx controller B 702 can tune the first tunable phase shifting component B 724a such that the second frequency band is phase shifted by an amount different than the third frequency band. For example, if the signal in the second frequency band is phase shifted by 140 degrees and the third frequency band is propagated by the back of the first amplifier B314a, the reflection of the leaving bandpass filter B313a, and the forward of the first amplifier B314b. The propagation is phase shifted by 130 degrees, and the DRx controller B 702 can tune the first tunable phase shifting component B 724a to phase shift the second frequency band by -70 degrees (or 110 degrees) and phase shift the third frequency band by -65 degrees ( Or 115 degrees).

The DRx controller B 702 can similarly tune the second phase shifting component B 724b and the third phase shifting component B 724c.

As another example, if the band selection signal indicates that the first path, the second path, and the fourth path (via the fourth amplifier B 314d) will be activated, the DRx controller B 702 can tune the first tunable phase shifting component B 724a such that 1) for along the second path (in the second band) In terms of the propagated signal, the initial signal is in phase with the reflected signal that propagates back along the first path, is reflected off the bandpass filter B313a and propagates forward through the first path; and (2) is along the fourth path (at In the case of the propagated signal at the fourth frequency band, the initial signal is in phase with the reflected signal that propagates back along the first path, is reflected off the bandpass filter B313a and propagates forward via the first path.

The DRx controller B 702 can tune the variable components of the tunable phase shifting components B724a through B724d to have different sets of different frequency bands.

In some implementations, the tunable phase shifting components B724a through B724d are replaced with fixed phase shifting components that are not tunable or that are not controlled by the DRx controller B702. Each of the phase shifting components disposed along a corresponding one of the paths corresponding to one frequency band can be configured to phase shift each of the other frequency bands such that the initial signal along the other path and the along path One of them back-propagates, reflects off the corresponding bandpass filter, and the reflected signals propagating forward through one of the paths are in phase.

For example, the third phase shifting component B 724c can be fixed and configured to: (1) phase shift the first frequency band such that the initial signal along the third path (propagating along the first path) Back-propagating, reflecting off the third bandpass filter B313c and propagating the forward signal via the third path in phase; (2) phase shifting the second frequency band such that at the second frequency (propagating along the second path) The initial signal is in phase with the reflected signal traveling back along the third path, reflected off the third bandpass filter B313c and propagating forward via the third path; and (3) phase shifting the fourth frequency band such that at the fourth The initial signal at frequency (propagating along the fourth path) is in phase with the reflected signal that propagates back along the third path, is reflected off the third bandpass filter B313c, and propagates forward via the third path. Other phase shifting components can be similarly fixed and configured.

Accordingly, the DRx module B 710 includes a DRx controller B 702 that is configured to selectively initiate one or more of a plurality of paths between the input of the DRx module B 710 and the output of the DRx module B 710 . The DRx module B710 further includes a plurality of amplifiers B314a to B314d, each of the plurality of amplifiers B314a to B314d being along a plurality of The corresponding one of the paths is placed and configured to amplify the signal received at the amplifier. The DRx module further includes a plurality of phase shifting components B724a through B724d, each of the plurality of phase shifting components B724a through B724d being disposed along a corresponding one of the plurality of paths and configured to pass signals of the phase shifting component Phase shift.

In some implementations, the first phase shifting component B 724a is disposed along a first path corresponding to the first frequency band (eg, the frequency band of the first bandpass filter B 313a) and configured to pass through the first phase shifting component B 724a The second frequency band of the signal (e.g., the frequency band of the second band pass filter B 313b) is phase shifted such that the initial signal propagating along the second path corresponding to the second frequency band is at least partially in phase with the reflected signal propagating along the first path.

In some implementations, the first phase shifting component B 724a is further configured to phase shift a third frequency band of the signal passing through the first phase shifting component B 724a (eg, the frequency band of the third bandpass filter B 313c) such that The initial signal propagating along the third path of the third frequency band is at least partially in phase with the reflected signal propagating along the first path.

17 shows that in some embodiments, the diversity receiver configuration BC1000 can include a DRx module BC1010 having tunable impedance matching components disposed at the input and output. The DRx module BC 1010 can include one or more tunable impedance matching components disposed at one or more of the inputs and outputs of the DRx module BC1010. In particular, the DRx module BC 1010 can include an input tunable impedance matching component BC 1016 disposed at the input of the DRx module BC 1010, an output tunable impedance matching component BC 1017 disposed at the output of the DRx module BC 1010, or both.

It is unlikely that multiple frequency bands received on the same diversity antenna 140 will achieve an ideal impedance match. Tunable input impedance matching group in order to match each frequency band using a tight matching circuit The BC 1016 can be implemented at the input of the DRx module BC 1010 and controlled by the DRx controller BC 1002 (eg, based on a band selection signal from the communication controller). For example, the DRx controller BC 1002 can tune the tunable input impedance matching component BC 1016 based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters. Thus, in response to the band select signal, the DRx controller BC 1002 can transmit the input impedance tuning signal to the tunable input impedance matching component BC 1016 to tune the tunable input impedance matching component (or its variable components) according to the tuning parameters.

The tunable input impedance matching component BC1016 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit. In particular, the tunable input impedance matching component BC1016 can include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the input of the DRx module BC1010 and the input of the first multiplexer BC311, or can be connected between the input of the DRx module BC1010 and the ground voltage.

Similarly, where only one transmission line 135 (or at least very few transmission lines) carries signals for many frequency bands, it is unlikely that multiple frequency bands will achieve an ideal impedance match. To match each frequency band using a tight matching circuit, tunable input impedance matching component BC1017 can be implemented at the input of DRx module BC1010 and controlled by DRx controller BC1002 (eg, based on a band selection signal from the communications controller). For example, the DRx controller BC 1002 can tune the tunable output impedance matching component BC 1017 based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters. Thus, in response to the band select signal, the DRx controller BC 1002 can transmit an output impedance tuning signal to the tunable output impedance matching component BC 1017 to tune the tunable output impedance matching component (or its variable components) based on the tuning parameters.

The tunable output impedance matching component BC1017 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit. In particular, the tunable output impedance matching component BC1017 can include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the output of the second multiplexer BC312 and the output of the DRx module BC1010, or can be connected between the output of the second multiplexer BC312 and the ground voltage.

FIG. 18 shows that in some embodiments, the diversity receiver configuration BC1100 can include a DRx module BC1110 having a plurality of tunable components. The diversity receiver configuration BC1100 includes a DRx module BC1110 having an input coupled to the antenna 140 and an output coupled to the transmission line 135. The DRx module BC1110 includes several paths between the input and output of the DRx module BC1110. In some implementations, the DRx module BC 1110 includes one or more bypass paths (not shown) between the inputs and outputs initiated by one or more bypass switches controlled by the DRx controller BC1102.

The DRx module BC1110 includes a plurality of multiplexer paths including an input multiplexer BC311 and an output multiplexer BC312. The multiplexer path includes a number of open module paths (shown in the figure) including tunable input impedance matching component BC1016, input multiplexer BC311, bandpass filters BC313a through BC313d, tunable impedance matching Components BC934a through BC934d, amplifiers BC314a through BC314d, tunable phase shifting components BC724a through BC724d, output multiplexer BC312, and tunable output impedance matching component BC1017. The multiplexer path can include one or more shutdown module paths (not shown) as described herein. As also described herein, amplifiers BC314a through BC314d can be variable gain amplifiers and/or variable current amplifiers.

The DRx controller BC1102 is configured to selectively initiate one or more of a plurality of paths between the input and the output. In some implementations, the DRx controller BC1102 is configured to selectively initiate one or more of a plurality of paths based on a band selection signal received by the DRx controller BC1102 (eg, from a communication controller). The DRx controller BC902 can selectively initiate the path by, for example, enabling or disabling the amplifiers BC314a through BC314d, controlling the multiplexers BC311, BC312, or via other mechanisms as described herein. In some implementations, the DRx controller BC1102 is configured to send an amplifier control signal to the minute One or more of the amplifiers BC314a through BC314d are placed along one or more of the initiated paths. The amplifier control signal controls the gain (or current) of the amplifier to which it is sent.

The DRx controller BC1102 is configured to tune one or more of the tunable input impedance matching component BC1016, the tunable impedance matching components BC934a through BC934d, the tunable phase shifting components BC724a through BC724d, and the tunable output impedance matching component BC1017. . For example, the DRx controller BC 1102 can tune the tunable component based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters. Thus, in response to the band selection signal, the DRx controller BC 1101 can transmit the tuning signal to the tunable component (of the active path) to tune the tunable component (or its variable components) based on the tuning parameters. In some implementations, the DRx controller BC1102 tunes the tunable component based at least in part on an amplifier control signal that is transmitted to control the gain and/or current of the amplifiers BC314a through BC314d. In various implementations, one or more of the tunable components can be replaced with a fixed component that is not controlled by the DRx controller BC1102.

It will be appreciated that tuning of one of the tunable components can affect the tuning of other tunable components. Thus, the tuning parameters for the first tunable component in the lookup table can be based on tuning parameters for the second tunable component. For example, tuning parameters for tunable phase shifting components BC724a through BC724d may be based on tuning parameters for tunable impedance matching components BC934a through BC934d. As another example, tuning parameters for tunable impedance matching components BC934a through BC934d may be based on tuning parameters for tunable input impedance matching component BC1016.

19 shows an embodiment of a flowchart representation of a method of processing an RF signal. In some implementations (and as detailed below as an example), method BC 1200 is performed by a controller, such as DRx controller BC1102 in FIG. In some implementations, method BC1200 is performed by processing logic including hardware, firmware, software, or a combination thereof. In some implementations, method BC1200 executes code execution by a processor stored in a non-transitory computer readable medium (eg, memory). Briefly, method BC1200 includes receiving a band selection signal and following one or more The received RF signal is routed through the tuned path to process the received RF signal.

Method BC 1200 begins at block BC 1210 with the controller receiving a band select signal. The controller may receive the band selection signal from another controller or may receive a band selection signal from a cellular base station or other external source. The band selection signal may indicate one or more frequency bands over which the wireless device will transmit and receive the RF signal. In some implementations, the band selection signal indicates a group band for carrier set communication.

At block BC 1220, the controller selectively activates one or more paths of the diversity receiver (DRx) module based on the band selection signal. As described herein, a DRx module can include a number between one or more inputs (coupled to one or more antennas) and one or more outputs (coupled to one or more transmission lines) of a DRx module. Paths. The path can include a bypass path and a multiplexer path. The multiplexer path can include opening the module path and closing the module path.

The controller can control one or more by, for example, opening or closing one or more bypass switches, enabling or disabling the amplifier disposed along the path via the amplifier enable signal, via the splitter control signal, and/or the combiner control signal Multiple multiplexers or selectively initiate one or more of a plurality of paths via other mechanisms. For example, the controller can open or close the switch disposed along the path or set the gain of the amplifier disposed along the path to substantially zero.

At block BC 1230, the controller sends a tuning signal to one or more tunable components disposed along one or more of the initiated paths. The tunable component can include a tunable impedance matching component disposed at an input of the DRx module, a plurality of tunable impedance matching components disposed along the plurality of paths, a plurality of tunable phase shifting components disposed along the plurality of paths, respectively One or more of the tunable output impedance matching components disposed at the output of the DRx module.

The controller can tune the tunable component based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters. Thus, in response to the band selection signal, the DRx controller can transmit the tuning signal to the tunable component (of the active path) to tune the tunable component (or its variable components) based on the tuning parameters. In some In implementations, the controller tunes the tunable component based at least in part on an amplifier control signal that is transmitted to control the gain and/or current of one or more amplifiers disposed along one or more of the initiated paths, respectively.

Example C: Impedance Offset Component

15 shows that in some embodiments, the diversity receiver configuration C800 can include a DRx module C 810 having one or more impedance matching components C834a through C834b. The DRx module C810 includes two paths: an input from the DRx module C810, coupled to the antenna 140, and an output from the DRx module C810 coupled to the transmission line 135.

In the DRx module C810 of FIG. 15 (as in the DRx module B610 of FIG. 11), the signal splitter and the band pass filter are implemented as a duplexer C611. The duplexer C611 includes an input coupled to the antenna, a first output coupled to the first impedance matching component C834a, and a second output coupled to the second impedance matching component C834b. At the first output, duplexer C611 outputs a signal filtered to the first frequency band received at the input (eg, from antenna 140). At the second output, duplexer C611 outputs a signal that is received at the input and filtered to the second frequency band.

Each of the impedance matching components C834a to C634d is disposed between the duplexer C611 and the amplifiers C314a to C314b. As described herein, each of amplifiers C314a through C314b is placed along the corresponding one of the paths and configured to amplify the signal received at the amplifier. The outputs of amplifiers C314a through C314b are fed to signal combiner C612.

The signal combiner C612 includes a first input coupled to the first amplifier C314a, a second input coupled to the second amplifier C314b, and an output coupled to the output of the DRx module C610. The signal at the output of the signal combiner is the sum of the signals at the first input and the second input.

When a signal is received by antenna 140, the signal is filtered by duplexer C611 to a first frequency band and propagates along a first path via first amplifier C314a. Similarly, the signal is filtered by the duplexer C611 to the second frequency band and propagates along the second path via the second amplifier C314b.

Each of the paths can be characterized as a noise index and gain. Noise signal for each path The number is a representation of the degradation of the signal-to-noise ratio (SNR) caused by the amplifier and impedance matching components placed along the path. In particular, the noise index for each path is the difference between the SNR at the input of impedance matching components C834a through C834b and the decibel (dB) between the SNRs at the outputs of amplifiers C314a through C314b. Therefore, the noise index is a measure of the difference between the noise output of the amplifier and the noise output of an "ideal" amplifier with the same gain that does not produce noise. Similarly, the gain of each path is a representation of the gain caused by the amplifier and impedance matching components placed along the path.

The noise index and gain for each path can be different for different frequency bands. For example, the first path may have an intra-frequency noise index and an intra-frequency gain for the first frequency band and an out-of-band noise index and an out-of-band gain for the second frequency band. Similarly, the second path can have an intra-frequency noise index and an intra-frequency gain for the second frequency band and an out-of-band noise index and an out-of-band gain for the first frequency band.

The DRx module C810 can also be characterized as a different noise index and gain for different frequency bands. In particular, the noise index of the DRx module C810 is the difference between the SNR at the input of the DRx module C810 and the SNR at the output of the DRx module C810.

The noise index and gain for each path (under each frequency band) may depend, at least in part, on the impedance of impedance matching components C834a through C834b (under each frequency band). Therefore, it may be advantageous for the impedance of the impedance matching components C834a through C834b to minimize the intra-frequency noise index for each path and/or to maximize the intra-frequency gain for each path. Thus, in some implementations, each of the impedance matching components C834a through C834b is configured to reduce the intra-frequency noise index of its respective path and/or increase the intra-frequency gain of its respective path (compared to no A DRx module having the impedance matching components C834a through C834b).

Since the signals propagating along the two paths are combined by the signal combiner C612, the out-of-band noise generated or amplified by the amplifier can have a negative impact on the combined signal. For example, the out-of-band noise generated or amplified by the first amplifier C314a may increase the noise index of the DRx module C810 at the second frequency. Therefore, it can be advantageous for the impedance matching component C834a The impedance to C834b minimizes the out-of-band noise index for each path and/or minimizes the out-of-band gain for each path. Thus, in some implementations, each of the impedance matching components C834a through C834b is configured to reduce the out-of-band noise index of its respective path and/or reduce the out-of-band gain of its respective path (compared to no A DRx module having the impedance matching components C834a through C834b).

The impedance matching components C834a through C834b can be implemented as passive circuits. In particular, impedance matching components C834a through C834b can be implemented as RLC circuits and include one or more passive components such as resistors, inductors, and/or capacitors. The passive components can be connected in parallel and/or in series and can be connected between the output of duplexer C611 and the inputs of amplifiers C314a through C314b, or can be connected between the output of duplexer C611 and the ground voltage. In some implementations, impedance matching components C834a through C834b are integrated into the same wafer as amplifiers C314a through C314b or on the same package.

As noted herein, for a particular path, it may be advantageous for the impedance of the impedance matching components C834a through C834b to minimize the intra-frequency noise index, maximize the intra-frequency gain, minimize the out-of-band noise index, and have an out-of-band gain. minimize. Designed to achieve impedance of all four of these targets with only two degrees of freedom (eg, impedance at the first frequency band and impedance at the second frequency band) or other various constraints (eg, number of components, cost, wafer gap) Matching components C834a through C834b can be challenging. Thus, in some implementations, the intra-frequency noise index minus the intra-frequency gain is minimized and the out-of-band noise index plus the out-of-band metric of the out-of-band gain is minimized. It may still be challenging to design impedance matching components C834a through C834b that achieve both of these goals with various constraints. Thus, in some implementations, the intra-frequency metric is minimized by a set of constraints, and the out-of-band metric is minimized by the set of constraints and additional constraints that do not increase the value of the intra-frequency metric by more than the threshold amount. (eg, 0.1 dB, 0.2 dB, 0.5 dB, or any other value). Thus, the impedance matching component is configured to reduce the intra-frequency noise index minus the intra-frequency gain's intra-frequency metric to within the threshold of the lowest intra-frequency metric, for example, the lowest possible intra-frequency that is subject to any constraints. the amount. The impedance matching component is further configured to reduce the out-of-band noise index plus the out-of-band metric of the out-of-band gain to an intra-band limited out-of-band minimum, eg, the lowest possible out-of-band metric subject to additional constraints, the additional The constraint is that the intra-frequency metric does not increase by more than the value of the threshold. In some implementations, the intra-frequency metric (weighted by intra-frequency factor) plus the out-of-band metric (weighted by out-of-band factor) is minimized by any constraints.

Thus, in some implementations, each of the impedance matching components C834a through C834b is configured to reduce the intra-frequency metric (intra-frequency noise index minus intra-frequency gain) of its respective path (eg, by reducing the frequency) Internal noise index, increased intra-frequency gain, or both). In some implementations, each of the impedance matching components C834a through C834b is further configured to reduce the out-of-band metric of its individual paths (out-of-band noise index plus out-of-band gain) (eg, by reducing out-of-band) Noise index, reduced out-of-band gain, or both).

In some implementations, by reducing the out-of-band metric, impedance matching components C834a through C834b reduce the noise index of DRx module C810 in one or more of the frequency bands without substantially increasing the noise index in other frequency bands.

16 shows that in some embodiments, the diversity receiver configuration C900 can include a DRx module C910 having tunable impedance matching components C934a through C934d. Each of the tunable impedance matching components C934a through C934d can be configured to present an impedance controlled by an impedance tuning signal received from the DRx controller C902.

The diversity receiver configuration C900 includes a DRx module C910 having an input coupled to the antenna 140 and an output coupled to the transmission line 135. The DRx module C910 includes several paths between the input and output of the DRx module C910. In some implementations, the DRx module C910 includes one or more bypass paths (not shown) between the inputs and outputs initiated by one or more bypass switches controlled by the DRx controller C902.

The multiplexer path includes a plurality of open module paths (shown in the figure), and the open module paths include an input multiplexer C311 and a band pass filter C313a to C313d, tunable impedance matching components C934a through C934d, amplifiers C314a through C314d, and output multiplexer C312. The multiplexer path can include one or more shutdown module paths (not shown) as described herein. As also described herein, amplifiers C314a through C314d can be variable gain amplifiers and/or variable current amplifiers.

The tunable impedance matching components C934a through C934b can be tunable T circuits, tunable PI circuits, or any other tunable matching circuit. The tunable impedance matching components C934a through C934d may include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the output of the input multiplexer C311 and the inputs of the amplifiers C314a to C314d, or can be connected between the output of the input multiplexer C311 and the ground voltage.

The DRx controller C902 is configured to selectively initiate one or more of a plurality of paths between the input and the output. In some implementations, the DRx controller C902 is configured to selectively initiate one or more of the plurality of paths based on a band selection signal received by the DRx controller C 902 (eg, from the communication controller). The DRx controller C902 can selectively initiate the path by, for example, enabling or disabling the amplifiers C314a through C314d, controlling the multiplexers C311, C312, or via other mechanisms as described herein.

In some implementations, the DRx controller C902 is configured to tune the tunable impedance matching components C934a through C934d. In some implementations, the DRx controller C702 tunes the tunable impedance matching components C934a through C934d based on the band selection signal. For example, DRx controller C 902 can tune tunable impedance matching components C934a through C934d based on a lookup table that associates the frequency bands (or sets of frequency bands) indicated by the band select signals with tuning parameters. Thus, in response to the band select signal, the DRx controller C902 can transmit an impedance tuning signal to the tunable impedance matching components C934a through C934d of each active path to tunable the impedance matching component (or its variable) based on the tuning parameters. Component) to tune.

In some implementations, the DRx controller C 902 is based at least in part on transmission to control amplification The amplifier control signals of the gains and/or currents of the C314a through C314d are tuned to the tunable impedance matching components C934a through C934d.

In some implementations, the DRx controller C902 is configured to tune the tunable impedance matching components C934a through C934d of each active path to minimize (or decrease) the intra-frequency noise index and maximize the intra-frequency gain. (or increase), the out-of-band noise index of each of the other active paths is minimized (or reduced), and/or the out-of-band gain of each other active path is minimized (or decreased).

In some implementations, the DRx controller C902 is configured to tune the tunable impedance matching components C934a through C934d of each active path to minimize intra-frequency metrics (intra-frequency noise index minus intra-frequency gain) (or lower) and the out-of-band metric (out-of-band noise index plus out-of-band gain) of each other active path is minimized (or reduced).

In some implementations, the DRx controller C902 is configured to tune the tunable impedance matching components C934a through C934d of each active path such that the intra-frequency metric is minimized (or reduced) subject to a set of constraints, and The out-of-band metrics for each of the other active paths are minimized (or reduced) by the set of constraints and additional constraints that do not increase by more than the threshold amount (eg, 0.1 dB). , 0.2dB, 0.5dB or any other value).

Thus, in some implementations, the DRx controller C902 is configured to tune the tunable impedance matching components C934a through C934d of each active path such that the tunable impedance matching component subtracts the intra-frequency noise index from the frequency The intra-frequency metric of the gain is reduced to within the threshold of the intra-frequency metric minimum, for example, the smallest intra-frequency metric that is subject to any constraints. The DRx controller C902 can be further configured to tune the tunable impedance matching components C934a through C934d of each active path such that the tunable impedance matching component adds the out-of-band noise index to the out-of-band metric of the out-of-band gain. Decrease to the intra-band restricted out-of-band minimum, for example, the smallest possible out-of-band metric subject to additional constraints that do not increase the value of the intra-frequency metric by more than the threshold amount.

In some implementations, the DRx controller C902 is configured to tune the tunable impedance matching components C934a through C934d of each active path such that the intra-frequency metric (by intra-frequency factor weighting) is added for other purposes. The composite metric of the out-of-band metric for each of the intermediate paths (weighted by the out-of-band factor of each of the other active paths) is minimized (or reduced) by any constraints.

The DRx controller C902 can tune the variable components of the tunable impedance matching components C934a through C934d to have different values for different frequency band groups.

In some implementations, the tunable impedance matching components C934a through C934d are replaced with fixed impedance matching components that are not tunable or that are not controlled by the DRx controller C902. Each of the impedance matching components disposed along a corresponding one of the paths corresponding to one frequency band may be configured to reduce (or minimize) the intra-frequency metric of the one frequency band and reduce (or minimize) other frequency bands An out-of-band metric of one or more (eg, each of the other frequency bands).

For example, the third impedance matching component C934c can be fixed and configured to: (1) reduce the intra-frequency metric of the third frequency band; (2) reduce the out-of-band metric of the first frequency band; (3) lower the second frequency band; The out-of-band metric; and/or (4) the out-of-band metric of the fourth band. Other impedance matching components can be similarly fixed and configured.

Accordingly, the DRx module C910 includes a DRx controller C902 that is configured to selectively enable one or more of a plurality of paths between the input of the DRx module C910 and the output of the DRx module C910. The DRx module C910 further includes a plurality of amplifiers C314a through C314d, each of the plurality of amplifiers C314a through C314d being disposed along a corresponding one of the plurality of paths and configured to amplify the signal received at the amplifier. The DRx module further includes a plurality of impedance matching components C934a through C934d, each of the plurality of phase shifting components C934a through C934d being disposed along a corresponding one of the plurality of paths and configured to reduce the one of the plurality of paths At least one of an out-of-band noise index or an out-of-band gain.

In some implementations, the first impedance matching component C934a is disposed along a first path corresponding to the first frequency band (eg, the frequency band of the first band pass filter C313a) and configured to reduce At least one of an out-of-band noise index or an out-of-band gain corresponding to a second frequency band of the second path (eg, a frequency band of the second band pass filter C313b).

17 shows that in some embodiments, the diversity receiver configuration BC1000 can include a DRx module BC1010 having tunable impedance matching components disposed at the input and output. The DRx module BC 1010 can include one or more tunable impedance matching components disposed at one or more of the inputs and outputs of the DRx module BC1010. In particular, the DRx module BC 1010 can include an input tunable impedance matching component BC 1016 disposed at the input of the DRx module BC 1010, an output tunable impedance matching component BC 1017 disposed at the output of the DRx module BC 1010, or both.

It is unlikely that multiple frequency bands received on the same diversity antenna 140 will achieve an ideal impedance match. To match each frequency band using a tight matching circuit, tunable input impedance matching component BC1016 can be implemented at the input of DRx module BC1010 and controlled by DRx controller BC1002 (eg, based on a band selection signal from the communications controller). For example, the DRx controller BC 1002 can tune the tunable input impedance matching component BC 1016 based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters. Thus, in response to the band select signal, the DRx controller BC 1002 can transmit the input impedance tuning signal to the tunable input impedance matching component BC 1016 to tune the tunable input impedance matching component (or its variable components) according to the tuning parameters.

The tunable input impedance matching component BC1016 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit. In detail, tunable input impedance matching components The BC 1016 may include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the input of the DRx module BC1010 and the input of the first multiplexer BC311, or can be connected between the input of the DRx module BC1010 and the ground voltage.

Similarly, where only one transmission line 135 (or at least very few transmission lines) carries signals for many frequency bands, it is unlikely that multiple frequency bands will achieve an ideal impedance match. To match each frequency band using a tight matching circuit, tunable input impedance matching component BC1017 can be implemented at the input of DRx module BC1010 and controlled by DRx controller BC1002 (eg, based on a band selection signal from the communications controller). For example, the DRx controller BC 1002 can tune the tunable output impedance matching component BC 1017 based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters. Thus, in response to the band select signal, the DRx controller BC 1002 can transmit an output impedance tuning signal to the tunable output impedance matching component BC 1017 to tune the tunable output impedance matching component (or its variable components) based on the tuning parameters.

The tunable output impedance matching component BC1017 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit. In particular, the tunable output impedance matching component BC1017 can include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the output of the second multiplexer BC312 and the output of the DRx module BC1010, or can be connected between the output of the second multiplexer BC312 and the ground voltage.

FIG. 18 shows that in some embodiments, the diversity receiver configuration BC1100 can include a DRx module BC1110 having a plurality of tunable components. The diversity receiver configuration BC1100 includes a DRx module BC1110 having an input coupled to the antenna 140 and an output coupled to the transmission line 135. The DRx module BC1110 includes several paths between the input and output of the DRx module BC1110. In some implementations, the DRx module BC1110 includes one or more of the inputs and outputs initiated by one or more bypass switches controlled by the DRx controller BC1102. Bypass path (not shown).

The DRx module BC1110 includes a plurality of multiplexer paths including an input multiplexer BC311 and an output multiplexer BC312. The multiplexer path includes a number of open module paths (shown in the figure) including tunable input impedance matching component BC1016, input multiplexer BC311, bandpass filters BC313a through BC313d, tunable impedance matching Components BC934a through BC934d, amplifiers BC314a through BC314d, tunable phase shifting components BC724a through BC724d, output multiplexer BC312, and tunable output impedance matching component BC1017. The multiplexer path can include one or more shutdown module paths (not shown) as described herein. As also described herein, amplifiers BC314a through BC314d can be variable gain amplifiers and/or variable current amplifiers.

The DRx controller BC1102 is configured to selectively initiate one or more of a plurality of paths between the input and the output. In some implementations, the DRx controller BC1102 is configured to selectively initiate one or more of a plurality of paths based on a band selection signal received by the DRx controller BC1102 (eg, from a communication controller). The DRx controller BC902 can selectively initiate the path by, for example, enabling or disabling the amplifiers BC314a through BC314d, controlling the multiplexers BC311, BC312, or via other mechanisms as described herein. In some implementations, the DRx controller BC1102 is configured to transmit an amplifier control signal to one or more of the amplifiers BC314a through BC314d disposed along one or more of the initiated paths, respectively. The amplifier control signal controls the gain (or current) of the amplifier to which it is sent.

The DRx controller BC1102 is configured to tune one or more of the tunable input impedance matching component BC1016, the tunable impedance matching components BC934a through BC934d, the tunable phase shifting components BC724a through BC724d, and the tunable output impedance matching component BC1017. . For example, the DRx controller BC 1102 can tune the tunable component based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters. Thus, in response to the band selection signal, the DRx controller BC 1101 can transmit the tuning signal to the tunable component (of the active path) to tunable components based on the tuning parameters (or its variable components) to tune. In some implementations, the DRx controller BC1102 tunes the tunable component based at least in part on an amplifier control signal that is transmitted to control the gain and/or current of the amplifiers BC314a through BC314d. In various implementations, one or more of the tunable components can be replaced with a fixed component that is not controlled by the DRx controller BC1102.

It will be appreciated that tuning of one of the tunable components can affect the tuning of other tunable components. Thus, the tuning parameters for the first tunable component in the lookup table can be based on tuning parameters for the second tunable component. For example, tuning parameters for tunable phase shifting components BC724a through BC724d may be based on tuning parameters for tunable impedance matching components BC934a through BC934d. As another example, tuning parameters for tunable impedance matching components BC934a through BC934d may be based on tuning parameters for tunable input impedance matching component BC1016.

19 shows an embodiment of a flowchart representation of a method of processing an RF signal. In some implementations (and as detailed below as an example), method BC 1200 is performed by a controller, such as DRx controller BC1102 in FIG. In some implementations, method BC1200 is performed by processing logic including hardware, firmware, software, or a combination thereof. In some implementations, method BC1200 executes code execution by a processor stored in a non-transitory computer readable medium (eg, memory). Briefly, method BC 1200 includes receiving a band select signal and routing the received RF signal along one or more tuned paths to process the received RF signal.

Method BC 1200 begins at block BC 1210 with the controller receiving a band select signal. The controller may receive the band selection signal from another controller or may receive a band selection signal from a cellular base station or other external source. The band selection signal may indicate one or more frequency bands over which the wireless device will transmit and receive the RF signal. In some implementations, the band selection signal indicates a group band for carrier set communication.

At block BC 1220, the controller selectively activates one or more paths of the diversity receiver (DRx) module based on the band selection signal. As described herein, a DRx module can include one or more inputs (coupled to one or more antennas) and one or more outputs (coupled) of a DRx module Several paths between one or more transmission lines). The path can include a bypass path and a multiplexer path. The multiplexer path can include opening the module path and closing the module path.

The controller can control one or more by, for example, opening or closing one or more bypass switches, enabling or disabling the amplifier disposed along the path via the amplifier enable signal, via the splitter control signal, and/or the combiner control signal Multiple multiplexers or selectively initiate one or more of a plurality of paths via other mechanisms. For example, the controller can open or close the switch disposed along the path or set the gain of the amplifier disposed along the path to substantially zero.

At block BC 1230, the controller sends a tuning signal to one or more tunable components disposed along one or more of the initiated paths. The tunable component can include a tunable impedance matching component disposed at an input of the DRx module, a plurality of tunable impedance matching components disposed along the plurality of paths, a plurality of tunable phase shifting components disposed along the plurality of paths, respectively One or more of the tunable output impedance matching components disposed at the output of the DRx module.

The controller can tune the tunable component based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters. Thus, in response to the band selection signal, the DRx controller can transmit the tuning signal to the tunable component (of the active path) to tune the tunable component (or its variable components) based on the tuning parameters. In some implementations, the controller tunes the tunable component based at least in part on an amplifier control signal transmitted to control gain and/or current of one or more amplifiers disposed along one or more of the initiated paths, respectively.

In particular, the aforementioned example C of the impedance offset component can be summarized as follows.

Example D: Postamplifier Filter

20 shows that in some embodiments, the diversity receiver configuration D400 can include a diversity receiver (DRx) module D410 having a plurality of band pass filters disposed at the output of the plurality of amplifiers D314a through D314d. D423a to D423d. The diversity receiver configuration D400 includes a DRx module D410 having an input coupled to the antenna 140 and an output coupled to the transmission line 135. The DRx module D410 includes a number of paths between the input and output of the DRx module D410. Each of the paths includes an input multiplexer D311, preamplifier bandpass filters D413a through D413d, amplifiers D314a through D314d, postamplifier bandpass filters D423a through D423d, and an output multiplexer D312.

The DRx controller D302 is configured to selectively initiate one or more of a plurality of paths between the input and the output. In some implementations, the DRx controller D302 is configured to selectively initiate one or more of the plurality of paths based on a band selection signal received by the DRx controller D302 (eg, from the communication controller). The DRx controller D302 can selectively initiate the path by, for example, enabling or disabling the amplifiers D314a through D314d, controlling the multiplexers D311, D312, or via other mechanisms.

The output of the DRx module D410 is transmitted to the diversity RF module D420 via the transmission line 135. The diversity RF module is different from the diversity RF module 320 of FIG. 3, because the diversity RF module D420 of FIG. 20 does not include downstream band pass filtering. Device. In some implementations (eg, as shown in FIG. 20), downstream multiplexer D321 can be implemented as a sampling switch.

The inclusion of post amplifier bandpass filters D423a through D423d in the DRx module D410 rather than the diversity RF module D420 provides several advantages. For example, as described in detail below, this configuration can improve the noise index of the DRx module D410, simplify the filtering design, and/or improve path isolation.

Each of the paths of the DRx module D410 can be characterized as a noise index. The noise index for each path is a representation of the decrease in the signal-to-noise ratio (SNR) produced by propagation along the path. In particular, the noise index for each path can be expressed as the decibel between the SNR at the input of the preamplifier bandpass filters D413a through D413d and the SNR at the output of the postamplifier bandpass filters D423a through D4234b ( The difference between dB). The noise index for each path can vary for different frequency bands. For example, the first path may have an intra-frequency noise index of the first frequency band and an out-of-band noise index of the second frequency band. Similarly, the second path may have an intra-frequency noise index of the second frequency band and an out-of-band noise index of the first frequency band.

The DRx module D410 can also be characterized as having different noise indices for different frequency bands. In particular, the noise index of the DRx module D410 is the difference between the SNR at the input of the DRx module D410 and the SNR at the output of the DRx module D410.

Since the signals propagating along the two paths are combined by the output multiplexer D312, The out-of-band noise generated or amplified by the amplifier can have a negative impact on the combined signal. For example, the out-of-band noise generated or amplified by the first amplifier D314a may increase the noise index of the DRx module D410 at the second frequency. Therefore, placing the post-amplifier bandpass filter D423a along the path reduces the out-of-band noise and reduces the noise index of the DRx module D410 at the second frequency.

In some implementations, the preamplifier bandpass filters D413a through D413d and the postamplifier bandpass filters D423a through D423d can be designed to be complementary, thereby simplifying filter design and/or achieving with fewer components at reduced cost. Similar performance. For example, placing the post-amplifier bandpass filter D423a along the first path can attenuate the frequency more strongly, while placing the preamplifier bandpass filter D413a along the first path edge attenuates the frequency more attenuated. As an example, the preamplifier bandpass filter D413a can attenuate frequencies below the first frequency band more than frequencies above the first frequency band. Complementarily, the post amplifier bandpass filter D423a can attenuate more frequencies above the first frequency band than frequencies below the first frequency band. Thus, in summary, the preamplifier bandpass filter D413a and the postamplifier bandpass filter D423a use less components to attenuate all out-of-band frequencies. In general, one of the band pass filters disposed along the path may cause the frequency of the respective frequency bands below the path to be attenuated more than the frequency of the respective frequency bands, and the band pass filter disposed along the path The other can make the frequency higher than the respective frequency bands attenuate more than the frequency lower than the respective frequency bands. The preamplifier bandpass filters D413a through D413d and the postamplifier bandpass filters D423a through D423d may be otherwise complementary. For example, placing the preamplifier bandpass filter D413a along the first path can phase shift the signal by a few degrees, and placing the postamplifier bandpass filter D423a along the first path can phase shift the signal by a few degrees.

In some implementations, post amplifier bandpass filters D423a through D423d may improve the isolation of the path. For example, in the absence of a post amplifier bandpass filter, the signal propagating along the first path can be filtered by the preamplifier bandpass filter D413a to a first frequency and amplified by amplifier D314a. The signal may leak through the output multiplexer D312 to follow the second The path propagates back and is reflected from amplifier D314b, preamplifier bandpass filter D413b, or other components placed along the second path. If the reflected signal is out of phase with the initial signal, this can result in a weakening of the signal when the signal is combined by the output multiplexer D312. In contrast, by placing a post-amplifier bandpass filter along the second path and associated with the second frequency band, the post-amplifier bandpass filter D423b attenuates the leakage signal (mainly in the first frequency band), thereby reducing The effect of any reflected signal.

Accordingly, DRx module D410 includes a controller configured to selectively activate an input of a first multiplexer (eg, input multiplexer D311) and a second multiplexer (eg, an output multiplexer) One or more of the plurality of paths between the outputs of D312). The DRx module D410 further includes a plurality of amplifiers D314a through D314d, each of the plurality of amplifiers D314a through D314d being disposed along a corresponding one of the plurality of paths and configured to amplify the signal received at the amplifier. The DRx module D410 includes a first plurality of band pass filters (eg, post amplifier band pass filters D423a through D423d), each of the first plurality of band pass filters being disposed along a corresponding one of the plurality of paths The output of the corresponding one of the plurality of amplifiers D314a through D314d is configured to filter the signal received at the bandpass filter to a respective frequency band. As shown in FIG. 20, in some implementations, the DRx module D410 further includes a second plurality of band pass filters (eg, preamplifier band pass filters D413a through D413d), the second plurality of band pass filters Each of the plurality of paths is disposed at an input of a corresponding one of the plurality of amplifiers D314a through D314d and is configured to filter the signal received at the bandpass filter to a respective frequency band.

21 shows that in some embodiments, the diversity receiver configuration D450 can include a diversity RF module D460 having fewer amplifiers than the diversity receiver (DRx) module D410. As mentioned herein, in some implementations, diversity RF module D 460 may not include a band pass filter. Thus, in some implementations, one or more of the diversity RF modules D460 need not be band specific. In particular, the diversity RF module D460 can include one or more paths that are not mapped one-to-one with the path of the DRx module D410, each path including an amplifier D424. This mapping of paths (or corresponding amplifiers) can be stored in controller 120.

Thus, although the DRx module D410 includes a plurality of paths each corresponding to a frequency band, the diversity RF module D460 may include one or more paths that do not correspond to a single frequency band (input to the multiplexer of the self-diversity RF module D460) Input of D321).

In some implementations (as shown in FIG. 21), the diversity RF module D460 includes a single wideband or tunable amplifier D424 that amplifies the signal received from the transmission line 135 and outputs the amplified signal to the multiplexer D321. The multiplexer D321 includes a plurality of multiplexer outputs, each corresponding to a respective frequency band. In some implementations, multiplexer D321 can be implemented as a sampling switch. In some implementations, the diversity RF module D460 does not include any amplifiers.

In some implementations, the diversity signal is a single band signal. Thus, in some implementations, multiplexer D321 is a single-pole/multi-throw (SPMT) switch that routes a diversity signal based on a signal received from controller 120 to one of a plurality of outputs corresponding to a frequency band of a single-band signal. . In some implementations, the diversity signal is a multi-band signal. Thus, in some implementations, multiplexer D421 is a signal splitter that routes the diversity signal based on a splitter control signal received from controller 120 to two or more frequency bands corresponding to the multi-frequency signal in the plurality of outputs Two or more outputs. In some implementations, the diversity RF module D460 can be combined with the transceiver D330 into a single module.

In some implementations, the diversity RF module D460 includes a plurality of amplifiers, each corresponding to a set of frequency bands. The signal from transmission line 135 can be fed into a band splitter that outputs a higher frequency to the high frequency amplifier along the first path and a lower frequency to the low frequency amplifier along the second path. The output of each of the amplifiers can be provided to a multiplexer D321 that is configured to route signals to corresponding inputs of the transceiver D330.

22 shows that in some embodiments, the diversity receiver configuration D500 can include a DRx module D510 coupled to one or more shutdown module filters D513, D523. The DRx module D510 can include a package substrate D501 configured to receive a plurality of components and a receiving system implemented on the package substrate D501. The DRx module D510 can include one or more signal paths. The signal paths are routed away from the DRx module D 510 and can be used by a system integrator, designer or manufacturer to support filters for any desired frequency band.

The DRx module D510 includes a number of paths between the input and output of the DRx module D510. The DRx module D510 includes a bypass path between the input and the output that is initiated by the bypass switch D519 controlled by the DRx controller D502. Although FIG. 22 illustrates a single bypass switch D519, in some implementations, the bypass switch D519 can include a plurality of switches (eg, a first switch disposed to physically approach the input and a second switch disposed to physically approach the output) . As shown in Figure 22, the bypass path does not include a filter or amplifier.

The DRx module D510 includes a plurality of multiplexer paths, and the multiplexer paths include a first multiplexer D511 and a second multiplexer D512. The multiplexer path includes a plurality of open module paths, and the open multiplexer path includes a first multiplexer D511, preamplifier bandpass filters D413a to D413d implemented on the package substrate D501, and implemented on the package substrate D501. The amplifiers D314a to D314d, the post-amplifier bandpass filters D423a to D423d and the second multiplexer D512 implemented on the package substrate D501.

For example, the DRx controller D502 can set the gain along the path (eg, filters D313a through D313d, filter D513 and amplifiers D314a through D314d, amplifier D514) or by setting the gains of amplifiers D314a through D314d, amplifier D514. Turning the switch on or off is essentially zero.

23 shows that in some embodiments, the diversity receiver configuration D600 can include a DRx module D610 with tunable matching circuitry. In particular, the DRx module D610 can include one or more tunable matching circuits disposed at one or more of the inputs and outputs of the DRx module D610.

It is unlikely that multiple frequency bands received on the same diversity antenna 140 will achieve an ideal impedance match. To match each frequency band using a compact matching circuit, tunable input matching circuit D616 can be implemented at the input of DRx module D 610 and controlled by DRx controller D 602 (eg, based on a band selection signal from the communication controller). The DRx controller D 602 can tune the tunable input matching circuit D616 based on a lookup table that associates the frequency band (or set of frequency bands) with the tuning parameters. The tunable input matching circuit D616 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit. In particular, tunable output matching circuit D616 can include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the input of the DRx module D610 and the input of the first multiplexer D311, or can be connected between the input of the DRx module D610 and the ground voltage.

Similarly, where only one transmission line 135 (or at least few cables) carries signals for many frequency bands, it is not possible for multiple frequency bands to achieve ideal impedance matching. To match each frequency band using a compact matching circuit, tunable output matching circuit D617 can be implemented at the output of DRx module D610 and controlled by DRx controller D602 (eg, based on a band selection signal from the communication controller). The DRx controller D602 can be based on a band (or a set of bands) A lookup table associated with the tuning parameters is used to tune the tunable output matching circuit D618. The tunable input matching circuit D617 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit. In particular, tunable output matching circuit D617 can include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the output of the DRx module D610 and the output of the second multiplexer D312, or can be connected between the output of the DRx module D610 and the ground voltage.

Example E: Switched Network

24 shows that in some embodiments, the diversity receiver configuration E500 can include a DRx module E510 having a single pole/single throw switch E519. The DRx module E510 includes two paths: an input from the DRx module E510, coupled to the antenna 140, and an output from the DRx module E510 coupled to the transmission line 135. The DRx module E510 includes a plurality of amplifiers E514a through E514b, each of the plurality of amplifiers E514a through E514b being disposed along a corresponding one of the plurality of paths and configured to amplify the signal received at the amplifier. In some implementations, as shown in FIG. 24, at least one of the plurality of amplifiers includes a two-stage amplifier.

In the DRx module E510 of FIG. 24, the signal separator and the band pass filter are implemented as a duplexer E511. The duplexer E511 includes an input coupled to the antenna 140, a first output coupled to the phase shifting component E527a disposed along the first path, and a second output coupled to the second phase shifting component E527b disposed along the second path. . At the first output, duplexer E511 outputs a signal filtered to the first frequency band received at the input (eg, from antenna 140). At the second output, duplexer E511 outputs a signal that is received at the input and filtered to the second frequency band. In some implementations, the duplexer E511 can be replaced with a triplexer, quadruplexer, or any other multiplexer configured to separate the input signal received at the input of the DRx module E510 into A plurality of signals propagating along a plurality of paths in respective multiple frequency bands.

In some implementations, an output multiplexer or other signal combiner (such as the second multiplexer 312 of FIG. 3) disposed at the output of the DRx module can reduce the performance of the DRx module when receiving a single band signal. For example, an output multiplexer can attenuate a single-band signal or introduce noise into a single-band signal. In some implementations, when multiple amplifiers (such as amplifiers 314a through 314d of FIG. 3) are simultaneously enabled to support multi-band signals, each amplifier can each introduce not only intra-frequency noise for each of the other plurality of frequency bands. And introduces out-of-band noise.

The DRx module E510 of Figure 24 addresses some of these challenges. DRx module E510 includes the first A path is coupled to a single path/single throw (SPST) switch E519 of the second path. To operate in a single band mode for the first frequency band, switch E519 is placed in the open position, first amplifier E514a is enabled and second amplifier E514b is deactivated. Therefore, the single band signal in the first frequency band propagates from the antenna 140 to the transmission line 135 along the first path without switching loss. Similarly, to operate in the single band mode for the second frequency band, the switch E519 is placed in the open position, the first amplifier E514a is deactivated and the second amplifier E514b is enabled. Therefore, the single band signal in the second frequency band propagates from the antenna 140 to the transmission line 135 along the second path without switching loss.

In order to operate in a multi-band mode for the first frequency band and the second frequency band, the switch E519 is placed in the off position, the first amplifier E514a is enabled and the second amplifier E514b is deactivated. Accordingly, the first frequency band portion of the multi-band signal propagates along the first path via the first phase shifting component E527a, the first impedance matching component E526a, and the first amplifier E514a. The first frequency band portion is prevented from propagating back across the switch E519 and by the second phase shifting component E527b along the second path. In particular, the second phase shifting component E527b is configured to phase shift the first frequency band portion of the signal passing through the second phase shifting component E527b to maximize (or at least increase) the impedance at the first frequency band.

The second band portion of the multi-band signal propagates along the second path via the second phase shifting component E527b, across switch E519, and propagates along the first path via first impedance matching component E526a and first amplifier E314a. The second band portion is prevented from being propagated back by the first phase shifting component E527a along the first path. In particular, the first phase shifting component E527a is configured to phase shift the second frequency band portion of the signal passing through the first phase shifting component E527a to maximize (or at least increase) the impedance in the second frequency band.

Each of the paths can be characterized as a noise index and gain. The noise index for each path is a representation of the degradation of the signal-to-noise ratio (SNR) caused by the amplifiers and impedance matching components E526a through E526b disposed along the path. In particular, the noise index for each path is the SNR at the input of impedance matching components E526a through E526b and the output of amplifiers E314a through E314b. The difference in decibels (dB) between the SNRs. Therefore, the noise index is a measure of the difference between the noise output of the amplifier and the noise output of an "ideal" amplifier with the same gain that does not produce noise.

The noise index for each path can vary for different frequency bands. For example, the first path may have a first noise index of the first frequency band and a second noise index of the second frequency band. The noise index and gain for each path (under each frequency band) may depend, at least in part, on the impedance of impedance matching components E526a through E526b (under each frequency band). Therefore, it may be advantageous for the impedance of the impedance matching components E526a through E526b to minimize (or decrease) the noise index of each path.

In some implementations, the second impedance matching component E526b exhibits an impedance that minimizes (or reduces) the noise index of the second frequency band. In some implementations, the first impedance matching component E 526a minimizes (or reduces) the noise index of the first frequency band. Since the second frequency band portion of the multi-band signal can propagate partially along the first portion, in some implementations, the first impedance matching component E 526a minimizes (or reduces) the noise index including the first frequency band and the second frequency band The measure of the noise index.

The impedance matching components E526a through E526b can be implemented as passive circuits. In particular, impedance matching components E526a through E526b can be implemented as RLC circuits and include one or more passive components such as resistors, inductors, and/or capacitors. The passive components can be connected in parallel and/or in series and can be connected between the outputs of phase shifting components E527a through E527b and the inputs of amplifiers E514a through E514b, or can be connected between the output of phase shifting components E527a through E527b and the ground voltage.

Similarly, phase shifting components E527a through E527b can be implemented as passive circuits. In particular, phase shifting components E527a through E527b can be implemented as LC circuits and include one or more passive components, such as inductors and/or capacitors. The passive components can be connected in parallel and/or in series and can be connected between the output of the duplexer E511 and the input of the impedance matching components E526a to E526b or can be connected between the output of the duplexer E511 and the ground voltage.

25 shows that in some embodiments, the diversity receiver configuration E600 can include a DRx module E610 having tunable phase shifting components E627a through E627d. Each of the tunable phase shifting components E627a through E627d can be configured such that the phase shift of the signal through the tunable phase shifting component is controlled by a phase shifted tuning signal received from the controller.

The diversity receiver configuration E600 includes a DRx module E610 having an input coupled to the antenna 140 and an output coupled to the transmission line 135. The DRx module E610 includes several paths between the input and output of the DRx module E610. Each of the paths includes a multiplexer E311, bandpass filters E313a through E313d, tunable phase shifting components E627a through E627d, switching network E612, tunable impedance matching components E626a through E626d, and amplifiers E314a through E314d. As described herein, amplifiers E314a through E314d can be variable gain amplifiers and/or variable current amplifiers.

The tunable phase shifting components E627a through E627d may include one or more variable components, such as inductors and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the output of the multiplexer E311 and the input of the switching network E612, or can be connected between the output of the multiplexer and the ground voltage.

The tunable impedance matching components E626a through E626d can be tunable T circuits, tunable PI circuits, or any other tunable matching circuit. The tunable impedance matching components E626a through E626d may include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the output of the switching network E612 and the inputs of the amplifiers E314a to E314d, or can be connected between the output of the switching network E612 and the ground voltage.

The DRx controller E 602 is configured to selectively initiate one or more of a plurality of paths between the input and the output. In some implementations, the DRx controller E 602 is configured to selectively initiate one or more of the plurality of paths based on a band selection signal received by the DRx controller E 602 (eg, from the communication controller). The DRx controller E602 can control the multiplexer E311 and/or the switching network E612 by, for example, enabling or disabling the amplifiers E314a to E314d, or The path is selectively initiated via other mechanisms.

In some implementations, the DRx controller E 602 controls the switching network E 612 based on the band selection signal. The switching network includes a plurality of SPST switches, each of which is coupled to two of a plurality of paths. The DRx controller E 602 can send a switched signal (or multiple switched signals) to the switching network to turn a plurality of SPST switches on or off. For example, if the band selection signal indicates that the input signal includes the first frequency band and the second frequency band, the DRx controller E602 can turn off the switch between the first path and the second path. If the band selection signal indicates that the input signal includes the second frequency band and the fourth frequency band, the DRx controller E602 may turn off the switch between the second path and the fourth path. If the frequency band selection signal indicates that the input signal includes the first frequency band, the second frequency band, and the fourth frequency band, the DRx controller E602 can turn off both of the switches (and/or close the switch between the first path and the second path and a switch between a path and a fourth path). If the frequency band selection signal indicates that the input signal includes the second frequency band, the third frequency band, and the fourth frequency, the DRx controller E602 may turn off the switch between the second path and the third path and the switch between the third path and the fourth path. (and/or closing the switch between the second path and the third path and the switch between the second path and the fourth path).

In some implementations, the DRx controller E 602 is configured to tune the tunable phase shifting components E627a through E627d. In some implementations, the DRx controller E 602 can tune the tunable phase shifting components E627a through E627d based on the band selection signals. For example, DRx controller E 602 can tune tunable phase shift components E627a through E627d based on a lookup table that associates the frequency bands (or sets of frequency bands) indicated by the band select signals with tuning parameters. Thus, in response to the band selection signal, the DRx controller E 602 can transmit a phase shifted tuning signal to the tunable phase shifting components E627a through E627d in each of the active paths to tunable phase shifting components (or Variable component) to tune.

The DRx controller E 602 can be configured to tune the tunable phase shifting components E627a through E627d of each active path to maximize (or at least increase) the impedance in the frequency band corresponding to the other active paths. Therefore, if the first path and the third path are active, then The DRx controller E602 can tune the first phase shifting component E627a to maximize (or at least increase) the impedance in the third frequency band, however, if the first path and the fourth path are active, the DRx controller E602 can The first phase shifting component E627a is tuned to maximize (or at least increase) the impedance at the fourth frequency band.

In some implementations, the DRx controller E602 is configured to tune the tunable impedance matching components E626a through E626d. In some implementations, the DRx controller E 602 tunes the tunable impedance matching components E626a through E626d based on the band selection signals. For example, DRx controller E 602 can tune tunable impedance matching components E626a through E626d based on a lookup table that associates the frequency bands (or sets of frequency bands) indicated by the band select signals with tuning parameters. Thus, in response to the band select signal, the DRx controller E 602 can transmit the impedance tuning signal to the tunable impedance matching components E626a through E626d having the path of the active amplifier based on the tuning parameters.

In some implementations, the DRx controller E602 tunes the tunable impedance matching components E626a through E626d having the path of the active amplifier to minimize (or reduce) the noise index including the corresponding frequency band of each active path. measure.

In various implementations, one or more of tunable phase shifting components E627a through E627d or tunable impedance matching components E626a through E626d may be replaced with fixed components that are not controlled by DRx controller E602.

Figure 26 shows an embodiment of a flowchart representation of a method E700 of processing an RF signal. In some implementations (and as detailed below as an example), method E700 is performed by a controller, such as DRx controller E 602 in FIG. In some implementations, method E700 is performed by processing logic including hardware, firmware, software, or a combination thereof. In some implementations, method E700 is executed by a processor executing a program stored in a non-transitory computer readable medium (eg, a memory). Briefly, method E700 includes receiving a band selection signal and routing the received RF signal along one or more paths to process the received RF signal.

Method E700 begins at block E710 with the controller receiving a band select signal. control The device may receive a band selection signal from another controller or may receive a band selection signal from a cellular base station or other external source. The band selection signal may indicate one or more frequency bands over which the wireless device will transmit and receive the RF signal. In some implementations, the band selection signal indicates a group band for carrier set communication.

At block E720, the controller transmits an amplifier enable signal to the amplifier of the DRx module based on the band select signal. In some implementations, the band selection signal indicates a single frequency band and the controller transmits an amplifier enable signal to enable an amplifier disposed along a path corresponding to a single frequency band. The controller can send an amplifier enable signal to disable other amplifiers placed along other paths corresponding to other frequency bands. In some implementations, the band selection signal indicates a plurality of frequency bands, and the controller transmits an amplifier enable signal to enable an amplifier disposed along one of the paths corresponding to one of the plurality of frequency bands. The controller can send an amplifier enable signal to disable other amplifiers. In some implementations, the controller enables an amplifier disposed along a path corresponding to the lowest frequency band.

At block 730, the controller transmits an exchange signal to control a switched network of single-pole/single-throw (SPST) switches based on the band selection signal. The switching network includes a plurality of SPST switches coupled to a plurality of paths corresponding to the plurality of frequency bands. In some implementations, the band selection signal indicates a single frequency band and the controller transmits all of the switching signals that are turned on in the SPST switch. In some implementations, the band selection signal indicates a plurality of frequency bands, and the controller transmits a switching signal to turn off one or more of the SPST switches to couple paths corresponding to the plurality of frequency bands.

At block E740, the controller transmits the tuning signal to one or more tunable components based on the band selection signal. The tunable component can include one or more of a plurality of tunable phase shifting components or a plurality of tunable impedance matching components. The controller can tune the tunable component based on a lookup table that associates the frequency band (or set of frequency bands) indicated by the band selection signal with the tuning parameters. Thus, in response to the band selection signal, the DRx controller can transmit the tuning signal to the tunable component (of the active path) to tune the tunable component (or its variable components) based on the tuning parameters.

In particular, the aforementioned example E of the switched network can be summarized as follows.

27 shows that in some embodiments, the diversity receiver configuration F600 can include a DRx module F610 with tunable matching circuitry. In particular, the DRx module F610 can include one or more tunable matches disposed at one or more of the inputs and outputs of the DRx module F610. Circuit.

It is unlikely that multiple frequency bands received on the same diversity antenna 140 will achieve an ideal impedance match. To match each frequency band using a compact matching circuit, tunable input matching circuit F616 can be implemented at the input of DRx module F610 and controlled by DRx controller F602 (eg, based on a band selection signal from the communication controller). The DRx controller F602 can tune the tunable input matching circuit F616 based on a lookup table that associates the frequency band (or set of frequency bands) with the tuning parameters. The tunable input matching circuit F616 can be a tunable T circuit, a tunable PI power, or any other tunable matching circuit. In particular, tunable output matching circuit F616 can include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the input of the DRx module F610 and the input of the first multiplexer F311, or can be connected between the input of the DRx module F610 and the ground voltage.

Similarly, where only one transmission line 135 (or at least few cables) carries signals for many frequency bands, it is not possible for multiple frequency bands to achieve ideal impedance matching. To match each frequency band using a compact matching circuit, tunable output matching circuit F617 can be implemented at the output of DRx module F610 and controlled by DRx controller F602 (eg, based on a band selection signal from the communications controller). The DRx controller F602 can tune the tunable input matching circuit F618 based on a lookup table that associates the frequency band (or set of frequency bands) with the tuning parameters. The tunable output matching circuit F617 can be a tunable T circuit, a tunable PI circuit, or any other tunable matching circuit. In particular, tunable output matching circuit F617 can include one or more variable components such as resistors, inductors, and capacitors. The variable components can be connected in parallel and/or in series and can be connected between the output of the DRx module F610 and the output of the second multiplexer F312, or can be connected between the output of the DRx module F610 and the ground voltage.

28 shows that in some embodiments, the diversity receiver configuration F700 can include multiple transmission lines. Although FIG. 28 illustrates an embodiment having two transmission lines F735a through F735b and one antenna 140, the aspects described herein can be implemented with more than two transmission lines and/or (eg, Further described below in the embodiments of two or more antennas.

The diversity receiver configuration F700 includes a DRx module F710 coupled to the antenna 140. The DRx module F710 includes an input of the DRx module F710 (eg, coupled to the input of the antenna 140a) and an output of the DRx module (eg, coupled to the first output of the first transmission line F735a or coupled to the second transmission line F735b). Several paths between the second output). In some implementations, the DRx module F710 includes one or more bypass paths (not shown) between the inputs and outputs initiated by one or more bypass switches controlled by the DRx controller F702.

The DRx module F710 includes a plurality of multiplexer paths including an input multiplexer F311 and an output multiplexer F712. The multiplexer path includes a plurality of open module paths (shown in the figure) including input multiplexer F311, band pass filters F313a through F313d, amplifiers F314a through F314d, and output multiplexer F712. The multiplexer path can include one or more shutdown module paths (not shown) as described herein. As also described herein, amplifiers F314a through F314d can be variable gain amplifiers and/or variable current amplifiers.

The DRx controller F702 is configured to selectively initiate one or more of a plurality of paths. In some implementations, the DRx controller F702 is configured to selectively initiate one or more of the plurality of paths based on a band selection signal received by the DRx controller F702 (eg, from the communication controller). The DRx controller F702 can selectively initiate the path by, for example, enabling or disabling the amplifiers F314a through F314d, controlling the multiplexers F311, F712, or via other mechanisms as described herein.

To better utilize the plurality of transmission lines F735a through F735b, the DRx controller F702 can control the output multiplexer F712 based on the band selection signal to route each of the signals propagating along the path to the selected one of the transmission lines F735a through F735b. (or output the multiplexer output corresponding to transmission lines F735a to F735b).

In some implementations, if the band selection signal indicates that the received signal includes a single frequency band, the DRx controller F702 can control the output multiplexer F712 to propagate on the corresponding path. The signal is routed to a preset transmission line. The preset transmission line may be the same for all paths (and corresponding bands), such as when one of the transmission lines F735a to F735b is shorter, introducing less noise or otherwise being preferred. The preset transmission line can be different for different paths. For example, a path corresponding to the low frequency band may be routed to the first transmission line F735a and a path corresponding to the high frequency band may be routed to the second transmission line F735b.

Thus, in response to indicating a band selection signal indicating that the one or more RF signals at the input multiplexer F311 comprise a single frequency band, the DRx controller F702 can be configured to control the second multiplexer F712, thereby corresponding to The amplified RF signal received at the output multiplexer input of the single frequency band is routed to the preset output multiplexer output. As noted herein, the preset output multiplexer outputs may be different for different single frequency bands or the same for all frequency bands.

In some implementations, if the band selection signal indicates that the received signal includes two frequency bands, the DRx controller F702 can control the output multiplexer F712 to route the signal propagating along the path corresponding to the first frequency band to the first transmission line F735a, And the signal propagating along the path corresponding to the second frequency band is routed to the second transmission line F735b. Thus, even if both of the two bands are high frequency bands (or low frequency bands), signals propagating along the respective paths can be routed to different transmission lines. Similarly, in the case of three or more transmission lines, each of three or more frequency bands can be routed to a different transmission line.

Accordingly, in response to the band selection signal indicating that the one or more RF signals received at the input multiplexer F311 include the first frequency band and the second frequency band, the DRx controller F702 can be configured to control the second multiplexer F712, thereby An amplified RF signal received at an output multiplexer input corresponding to the first frequency band is routed to a first output multiplexer output and an amplified RF signal to be received at an output multiplexer input corresponding to the second frequency band Routed to the second output multiplexer output. As indicated herein, both the first frequency band and the second frequency band can be a high frequency band or a low frequency band.

In some implementations, if the band selection signal indicates that the received signal includes three frequencies Band, the DRx controller F702 can control the output multiplexer F712 to combine two of the signals propagating along two paths corresponding to both of the frequency bands and route the combined signals along one of the transmission lines and along the transmission line The other routes signals that propagate along a path corresponding to the third frequency band. In some implementations, the DRx controller F702 controls the output multiplexer F712 to combine two of the most recent three frequency bands (eg, two low frequency bands or two high frequency bands). Such an implementation simplifies impedance matching at the output of the DRx module F710 or at the input of the downstream module. In some implementations, the DRx controller F702 controls the output multiplexer F712 to combine two of the three bands that are furthest apart. Such an implementation simplifies band separation at downstream modules.

Accordingly, in response to the band selection signal indicating receipt of one or more RF signals at input multiplexer F311 including the first frequency band, the second frequency band, and the third frequency band, DRx controller F702 can be configured to control the second multiplex The device F712 performs the following operations: (a) combining the amplified RF signal received at the output multiplexer input corresponding to the first frequency band with the amplified RF signal received at the output multiplexer input corresponding to the second frequency band to Generating a combined signal; (b) routing the combined signal to a first output multiplexer output; and (c) routing the amplified RF signal received at an output multiplexer input corresponding to the third frequency band to a second Output multiplexer output. As noted herein, the first frequency band and the second frequency band can be the same among the three most recent or farthest frequency bands.

In some implementations, if the band selection signal indicates that the received signal includes four frequency bands, the DRx controller F702 can control the output multiplexer F712 to combine two of the signals propagating along two paths corresponding to both of the frequency bands. And routing the first combined signal along one of the transmission lines and routing both of the signals propagating along the two paths corresponding to the other two of the frequency bands and routing the second combined signal along the other of the transmission lines. In some implementations, the DRx controller F702 can control the output multiplexer F712 to combine three of the signals propagating along three paths corresponding to three of the frequency bands and route the combined signals along one of the transmission lines and along The other of the transmission lines routes the signal propagating along the path corresponding to the fourth frequency band number. This implementation may be beneficial when three of the frequency bands (e.g., all low frequency bands are close together and the fourth frequency band (e.g., high frequency band) is far apart.

In general, if the band selection signal indicates that the received signal includes more frequency bands than the presence of the transmission line, the DRx controller F702 can control the output multiplexer F712 to combine two or two along the corresponding two or more frequency bands. Two or more of the signals propagated by the above paths and routing the combined signals to one of the transmission lines. The DRx controller F702 can control the output multiplexer F712 to combine the most recent or farthest frequency bands.

Thus, depending on other signals propagating along other paths, the signal propagating along one of the paths can be routed by output multiplexer F712 to a different one of the transmission lines. As an example, when the third path is the only active path and is routed to the first transmission line F735a and when the fourth path (through the fourth amplifier F314d) is also active (and routed to the second transmission line 735b), along The signal propagating through the third path of the third amplifier F314c can be routed to the second transmission line F735b.

Accordingly, the DRx controller F702 can be configured to: control the output multiplexer F712 to route the amplified RF signal received at the output multiplexer input to the output multiplexer in response to the first band select signal Outputting; and controlling the output multiplexer to route the amplified RF signal received at the output multiplexer input to the second output multiplexer output in response to the second band select signal.

Therefore, the DRx module F710 constitutes a receiving system including a plurality of amplifiers F314a to F314d, and each of the plurality of amplifiers F314a to F314d is input along the receiving system (for example, the input of the DRx module F710 coupled to the antenna 140 and / or an additional input of the DRx module F710 coupled to other antennas) and an output of the receiving system (eg, an output of the DRx module F710 coupled to the transmission lines F735a to F735b and/or a DRx module coupled to other transmission lines) The corresponding one of the plurality of paths between the additional outputs of F710 is placed. Each of amplifiers F314a through F314d is configured to amplify the RF signals received at amplifiers F314a through F314d.

The DRx module F710 further includes an input multiplexer F311 configured to receive one or more RF signals at one or more input multiplexer inputs and to include the one or more RF signals Each of the outputs is output to one or more of the plurality of input multiplexer outputs for propagation along one or more of the plurality of paths. In some implementations, the DRx module F710 receives a single RF signal at a single input multiplexer input and is controlled by the DRx controller F702 to output a single RF signal to an input corresponding to each frequency band indicated in the band selection signal. One or more of the multiplexer outputs. In some implementations, the DRx module F710 receives a plurality of RF signals at a plurality of input multiplexer inputs (each corresponding to indicating a different set of one or more frequency bands in the band selection signal) and is controlled by DRx The device F702 controls to output each of the plurality of RF signals to one or more of the input multiplexer outputs corresponding to one or a plurality of frequency bands of the respective RF signals. Thus, in general, input multiplexer F311 receives one or more RF signals (each corresponding to one or more frequency bands) and is controlled by the DRx controller to follow one or more frequency bands corresponding to the RF signals. One or more paths route each RF signal.

The DRx module F710 further includes an output multiplexer F712 configured to receive one of the plurality of paths propagating along one or more of the plurality of paths at one or more respective output multiplexer inputs Or a plurality of amplified RF signals, and configured to output each of the one or more amplified RF signals to a plurality of output multiplexer outputs (each coupled to a plurality of output transmission lines F735a, respectively) The selected one of the F735b.

The DRx module F710 further includes a DRx controller F702 that is configured to receive a band select signal and control the input multiplexer and the output multiplexer based on the band select signal. As described herein, the DRx controller F702 controls the input multiplexer to route one or more RF signals corresponding to one or more frequency bands along one or more paths corresponding to one or more frequency bands of the RF signal. Each. As also described herein, the DRx controller F702 controls the output multiplexer to route each of the one or more amplified RF signals along one or more paths to a plurality of output multiplexer outputs. Selected to better Transmission lines F735a through F735b coupled to DRx module F710 are used.

In some implementations, if the band selection signal indicates that the received signal includes a plurality of frequency bands, the DRx controller F702 can control the output multiplexer F712 to combine all signals propagating along paths corresponding to the plurality of frequency bands and route the combined signals To one of the transmission lines. When other transmission lines are not available (eg, damaged or not present in a particular wireless communication configuration) and are responsive to controller signals received by a DRx controller F702 (eg, from a communication controller) that is unavailable to one of the transmission lines These implementations can be used when implemented.

Therefore, the DRx controller F702 can be configured to control upon receiving a band selection signal including one or more RF signals including multiple frequency bands at the input multiplexer F311 and in response to a controller signal indicating that the transmission line is not available. Output multiplexer F712 combines the plurality of amplified RF signals received at a plurality of output multiplexer inputs corresponding to the plurality of frequency bands to produce a combined signal and route the combined signal to the output multiplexer output.

Figure 29 shows an embodiment of an output multiplexer F812 that can be used for dynamic routing. The output multiplexer F812 includes a plurality of inputs F801a through F801d that are respectively coupled to amplifiers disposed along a plurality of paths corresponding to the plurality of frequency bands. The output multiplexer F812 includes a plurality of outputs F802a through F802b that are respectively coupled to a plurality of transmission lines. Each of the outputs F802a through F802b is coupled to an output of a respective combiner F820a through F820b. Each of the inputs F801a through F801d is coupled to the input of each of the combiners F820a through F820b via one of a set of single pole/single throw (SPST) switches F830. Switch F830 can be controlled via control bus F803 that can be coupled to the DRx controller.

FIG. 30 shows another embodiment of an output multiplexer F912 that can be used for dynamic routing. The output multiplexer F912 includes a plurality of inputs F901a through F901d that are respectively coupled to amplifiers disposed along a plurality of paths corresponding to the plurality of frequency bands. The output multiplexer F912 includes a plurality of outputs F902a through F902b that are respectively coupled to a plurality of transmission lines. Each of the outputs F902a through F902b is coupled to the output of each of the combiners F920a through F920b. The first input F901a is coupled to the input of the first combiner F920a and the fourth input F901d The input is coupled to the input of the second combiner F920d. The second input F901b is coupled to a first single pole/multiple throw (SPMT) switch F930a having an output coupled to each of the combiners F920a through F920b. Similarly, the third input F901c is coupled to a second SPMT switch F930b having an output coupled to each of the combiners F920a through F920b. Switches F930a through F930b can be controlled via a control bus F903 that can be coupled to the DRx controller.

Unlike the output multiplexer 812 of FIG. 8, the output multiplexer 912 of FIG. 9 does not allow each of the inputs 901a through 901d to be routed to any of the outputs 902a through 902b. Instead, the first input 901a is fixedly routed to the first output 902a and the fourth input 902d is fixedly routed to the second output 902b. This implementation may reduce the size of the control bus 903 or simplify the control logic of the DRx controller attached to the control bus 903.

Both the output multiplexer F812 of FIG. 29 and the output multiplexer F912 of FIG. 30 include first combiners F820a, F920a coupled to the first output multiplexer outputs F802a, F902a, and coupled to the second output. The second output combiners F820b and F920b of the F802b and F902b are output. In addition, both the output multiplexer F812 of FIG. 29 and the output multiplexer F912 of FIG. 30 are coupled to the first combiner F820a, F920a, and the second combiner via one or more switches (controlled by the DRx controller). The output multiplexers of both F820b and F920b are input to F801b and F901b. In the output multiplexer F812 of FIG. 29, the output multiplexer input F801b is coupled to the first combiner F820a and the second combiner F820b via two SPST switches. In the output multiplexer F912 of FIG. 30, the output multiplexer input F901b is coupled to the first combiner F920a and the second combiner F820b via a single SPMT switch.

FIG. 31 shows that in some embodiments, the diversity receiver configuration F1000 can include multiple antennas F1040a through F1040b. Although FIG. 31 illustrates an embodiment having one transmission line 135 and two antennas F1040a through F1040b, the aspects described herein may be implemented in embodiments having two or more transmission lines and/or more than two antennas.

The diversity receiver configuration F1000 includes a DRx module F1010 coupled to the first antenna F1040a and the second antenna F1040b. DRx module F1010 is included in the DRx module F1010 And (eg, coupled to the first input of the first antenna F1040a or coupled to the second input of the second antenna F1040b) and the output of the DRx module (eg, coupled to the output of the transmission line 135) Several paths. In some implementations, the DRx module F1010 includes one or more bypass paths (not shown) between the inputs and outputs initiated by one or more bypass switches controlled by the DRx controller F1002.

The DRx module F1010 includes a plurality of multiplexer paths including an input multiplexer F1011 and an output multiplexer F312. The multiplexer path includes a plurality of open module paths (shown in the figure) including input multiplexer F1011, band pass filters F313a through F313d, amplifiers F314a through F314d, and output multiplexer F312. The multiplexer path can include one or more shutdown module paths (not shown) as described herein. As also described herein, amplifiers F314a through F314d can be variable gain amplifiers and/or variable current amplifiers.

The DRx controller F1002 is configured to selectively initiate one or more of a plurality of paths. In some implementations, DRx controller F1002 is configured to selectively initiate one or more of a plurality of paths based on a band selection signal received by DRx controller F1002 (eg, from a communication controller). The DRx controller F1002 can selectively initiate the path by, for example, enabling or disabling the amplifiers F314a through F314d, controlling the multiplexers F1011, F312, or via other mechanisms as described herein.

In various diversity receiver configurations, antennas F1040a through F1040b can support various frequency bands. For example, in one implementation, the diversity receiver configuration can include a first antenna F1040a supporting the low and medium frequency bands and a second antenna F1040b supporting the high frequency band. Another diversity receiver configuration may include a first antenna F1040a supporting a low frequency band and a second antenna F1040b supporting a medium frequency band and a high frequency band. Yet another diversity receiver configuration may include only the first broadband antenna F1040a supporting the low, medium, and high frequency bands and may not have the second antenna F1040b.

The same DRx module F1010 can be based on antenna configuration signals (eg, received from a communication controller or stored in medium permanent memory or other fixed-line configuration and from permanent memory or other The fixed line configuration read) is used for all of these diversity receiver configurations via the control of the input multiplexer F1011 by the DRx controller F1002.

In some implementations, when the antenna configuration signal indicates that the diversity receiver configuration F1000 includes only a single antenna F1040a, the DRx controller F1002 can control the input multiplexer to route signals received at the single antenna F1040a to all paths (or All active paths as indicated by the band selection signal).

Thus, in response to indicating that the diversity receiver configuration includes an antenna configuration signal comprising a single antenna, the DRx controller F1002 can be configured to control the input multiplexer to route RF signals received at a single input multiplexer input to all A plurality of input multiplexer outputs or all of the plurality of input multiplexer outputs associated with one or more frequency bands of the RF signal.

In some implementations, the DRx controller F1002 can control the input when the antenna configuration signal indicates that the diversity receiver configuration F1000 includes the first antenna F1040a supporting the low frequency band and the second antenna F1040b supporting the middle frequency band and the high frequency band. The processor F1011 routes the signal received at the first antenna F1040a to the first path (including the first amplifier F314a) and routes the signal received at the second antenna F1040b to the second path (including the second amplifier F314b) ), the third path (including the third amplifier F314c) and the fourth path (including the fourth amplifier F314d), or at least one of the paths in effect as indicated by the band selection signal.

In some implementations, when the antenna configuration signal indicates that the diversity receiver configuration F1000 includes the first antenna F1040a supporting the low and medium frequency bands and the second antenna F1040b supporting the medium and high frequency bands and the high frequency band, the DRx controller F1002 may control input multiplexer F1011 to route signals received at first antenna F1040a to first path and second path and route signals received at second antenna F1040b to third path and fourth path Or at least one of the paths in effect as indicated by the band selection signal.

In some implementations, when the antenna configuration signal indicates that the diversity receiver configuration F1000 includes a first antenna F1040a supporting the low and medium frequency bands and a second antenna supporting the high frequency band At F1040b, the DRx controller F1002 can control the input multiplexer F1011 to route the signals received at the first antenna F1040a to the first path, the second path, and the third path, and will receive at the second antenna F1040b. The signal is routed to the fourth path, or at least one of the paths in effect as indicated by the band selection signal.

Therefore, depending on the diversity receiver configuration (as indicated by the antenna configuration signal), different routing edges from the input multiplexer input (coupled to one of the antennas F1040a to F1040b) can be routed by the input multiplexer F1011. A signal that is propagated by a particular path (eg, a third path).

Thus, the DRx controller F1002 can be configured to: control the input multiplexer F1011 in response to the first antenna configuration signal to route the RF signal received at the first input multiplexer input to the input And outputting the multiplexer F1011 in response to the second antenna configuration signal to route the RF signal received at the second input multiplexer input to the input multiplexer output.

In general, DRx controller F1002 can be configured to control input multiplexer F1011 to route received signals (each including one or more frequency bands) along a path corresponding to one or more frequency bands. In some implementations, input multiplexer F1011 can further function as a band splitter that outputs each of one or more frequency bands along a path corresponding to one or more frequency bands. As an example, the input multiplexer F1011 and the band pass filters F313a to F313d constitute this band splitter. In other implementations (as further described below), bandpass filters F313a through F313d and input multiplexer F1011 may be integrated in other ways to form a band splitter.

Figure 32 shows an embodiment of an input multiplexer F1111 that can be used for dynamic routing. The input multiplexer F1111 includes a plurality of inputs F1101a through F1101b that are respectively coupled to one or more antennas. Input multiplexer F1111 includes a plurality of outputs F1102a through F1102d that are respectively coupled (e.g., via a bandpass filter) to amplifiers disposed along a plurality of paths corresponding to a plurality of frequency bands. Each of the inputs F1101a through F1101b is coupled to each of the outputs F1102a through F1102d via one of a set of single-pole/single-throw (SPST) switches F1130 By. Switch F1130 can be controlled via control bus F1103 that can be coupled to the DRx controller.

Figure 33 shows another embodiment of an input multiplexer F1211 that can be used for dynamic routing. The input multiplexer F1211 includes a plurality of inputs F1201a through F1201b that are respectively coupled to one or more antennas. Input multiplexer F1211 includes a plurality of outputs F1202a through F1202d that are respectively coupled (e.g., via a bandpass filter) to amplifiers disposed along a plurality of paths corresponding to a plurality of frequency bands. The first input F1201a is coupled to the first output F1202a, the first multi-pole/single throw (MPST) switch F1230a, and the second MPST switch F1230b. The second input F1201b is coupled to the first MPST switch F1230a, the second MPST switch F1230b, and the fourth output F1202d. Switches F1230a through F1230b can be controlled via control bus F1203 that can be coupled to the DRx controller.

Unlike the input multiplexer F1111 of FIG. 32, the output multiplexer F1211 of FIG. 33 does not allow each of the F1201a through F1201b to be routed to any of the outputs F1202a through F1202d. The fact is that the first input F1201a is fixedly routed to the first output F1202a and the second input F1201b is fixedly routed to the fourth output F1202d. This implementation may reduce the size of the control bus F903 or simplify the control logic of the DRx controller attached to the control bus F903. Nonetheless, based on the antenna configuration signal, the DRx controller can control switches F1230a through F1230b to route signals from any of inputs F1201a through F1201b to second output F1202b and/or third output F1202c.

Both the input multiplexer F1111 of FIG. 32 and the input multiplexer F1211 of FIG. 33 function as a multi-knife/multi-throw (MPMT) switch. In some implementations, the input multiplexers F1111, F1211 include filters or matching components to reduce insertion loss. These filters or matching components can be designed together to have other components of the DRx module (eg, bandpass filters F313a through F313d of Figure 31). For example, input multiplexers and bandpass filters can be integrated into a single part to reduce the number of all components. As another example, an input multiplexer can be designed for a particular output impedance (eg, one that is not 50 ohms) and the band pass filter can be designed to match this impedance.

Figures 34-39 show various implementations of DRx modules with dynamic input routing and/or output routing. FIG. 34 shows that in some embodiments, DRx module F 1310 can include a single input and two outputs. The DRx module F1310 as a band splitter includes: a high and low duplexer F1311, which separates the input signal into the low frequency band and the middle and high frequency bands; and the double/eight throw switch F1312 (implemented as the first single/three throw switch and the first Two single/five throw switches; and various filter and band split duplexers. As described herein, the high and low duplexer F1311 and various filters and band split duplexers can be designed together.

Figure 35 shows that in some embodiments, DRx module F 1320 can include a single input and a single output. The DRx module F1320 as a band separator includes: a high and low duplexer F1321, which separates the input signal into the low frequency band and the middle and high frequency bands; and the double/eight throw switch F1322 (implemented as the first single/three throw switch and the first Two single/five throw switches; and various filter and band split duplexers. As described herein, the high and low duplexer F1321 and various filters and band split duplexers can be designed together.
