In the related art, for each channel in the rf circuit, a corresponding test socket is required to be provided for the rf research and development personnel to test. For example, as shown in fig. 1, the radio frequency circuit 1 includes a main diversity path 10 and a diversity path 11; a test socket 12 is provided for the main diversity path 10, and a test socket 13 is provided for the diversity path 11. However, the manner of disposing the test socket in the related art results in the test socket occupying a large amount of space on a PCB (Printed Circuit Board) and being costly.

Accordingly, the present disclosure solves the above-mentioned technical problems in the related art by improving the structure of the radio frequency circuit.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a radio frequency circuit according to an exemplary embodiment. As shown in fig. 2, the radio frequency circuit 2 includes a main diversity path 20, a diversity path 21, a test socket 22, and a changeover switch 23. Wherein, the test socket 22 can be electrically connected with a test device for the test device to accurately test the main diversity path 20 and the diversity path 21; one end (the right end in fig. 2 is taken as an example) of the changeover switch 23 is connected to the main diversity path 20 and the diversity path 21, respectively, and the other end (the left end in fig. 2 is taken as an example) is connected to the test socket 22. Based on the above-described configuration of the radio frequency circuit 2, the changeover switch 23 is switched to the first state to be conductive with the main collector path 20 in the case where the main collector path 20 is a target to be measured, and is switched to the second state to be conductive with the diversity path 21 in the case where the diversity path 21 is a target to be measured. Of course, fig. 2 illustrates a case where the radio frequency circuit 2 only includes one diversity path, and actually, the radio frequency circuit 2 may further include a plurality of diversity paths, and the principle of which may refer to the embodiment shown in fig. 2 and is not described herein again. Therefore, in the radio frequency circuit disclosed by the invention, the object (namely the target to be tested) connected with the test seat is switched through the selector switch, on one hand, accurate test on the main set channel and the diversity channel can be ensured to be realized by using the test seat, on the other hand, the test on the main set channel and the diversity channel in the radio frequency circuit can be completed only through the same test seat, and corresponding test seats do not need to be arranged aiming at the main set channel and the diversity channel respectively, so that the hardware cost is reduced, and the space occupied by the radio frequency circuit is reduced.

In the present embodiment, the changeover switch 23 may be switched to the first state in the case where the main collector path 20 is used for transmitting and receiving data. In other words, during testing, the main set path 20 is targeted for testing when the main set path 20 is used to transmit and receive data.

In the present embodiment, as shown in fig. 3, the rf circuit 2 may further include a connection socket 24, and it should be noted that the connection socket 24 occupies less space on the PCB than the test socket 22, but has lower precision when used for testing. For example, the test socket usually has a snap-down spring to ensure good contact between the test equipment in the factory and the motherboard (carrier of the rf circuit); and under the condition that can cable seat is as the test seat and directly tests, because can cable seat does not have the lower spring of detaining, can not guarantee that test equipment and mainboard contact are good, even the position only appears the small deviation, also will lead to the test data to appear great deviation. The connecting base 24 is connected to the other end of the switch 23 (the left end is taken as an example in fig. 2-3), and is conducted with the main collector 20 when the switch 23 is switched to the second state, so that the main collector is maintained in the data transmitting state. At the same time, the switch 23 is switched to the second state in the case where the diversity path 21 is used to receive data. As an exemplary embodiment, the connection seat 24 may include a cable seat; the changeover switch 23 includes a double pole double throw switch. It can be seen that although the connection socket has lower precision for testing than the test socket, it is only necessary to maintain the main bus 20 in the data transmitting state. In other words, when testing the diversity path 21, the accuracy requirement on the main diversity path 20 is not high, and it is sufficient to maintain the data connection (it can be understood that the main diversity path 20 can transmit and receive data), and the accurate test by the test socket 22 is required when receiving data on the diversity path 21.

For ease of understanding, the circuit testing device and the radio frequency circuit of the present disclosure are described in detail below by taking the circuit testing device as an example for testing the radio frequency circuit.

Referring to fig. 4, fig. 4 is a schematic diagram illustrating a test rf circuit according to an exemplary embodiment. As shown in fig. 4, the circuit testing apparatus 3 for testing the radio frequency circuit 2 in the above embodiment may include a testing module 30, a first testing pin 31, a first antenna 32, a control module 33, a second testing pin 34, and a second antenna 35.

The test module 30 is used for testing the main diversity path 20 and the diversity path 21. For example, the signal source may be a signal source for providing signals to the main diversity path 20 and the diversity path 21, calibrating whether the main diversity path 20 and the diversity path 21 are operating properly, and testing parameters related to the performance of the main diversity path 20 and the diversity path 21.

One end (the right end in fig. 4 is taken as an example) of the first testing pin 31 is used for electrically connecting with the testing seat 22 of the object to be tested, and the other end (the left end in fig. 4 is taken as an example) is electrically connected with the testing module 30.

The first antenna 32 is used to transmit and receive data in the case of being conductive with the main diversity path 20 and to receive data in the case of being conductive with the diversity path 21.

The control module 33 may be electrically connected with the switch 23 to switch the switch state of the switch 23.

In the present embodiment, the connecting socket 24 is connected to the other end of the switch 23 (the left end is taken as an example in fig. 4), and is conducted with the main set path 20 when the switch 23 is switched to the second state, so that the main set path 20 is maintained in the data transmitting state, and the switch 23 is switched to the second state when the diversity path 21 is used for receiving data. Based on the above configuration, the circuit test apparatus of the present disclosure may further include: a second testing pin 34, one end (the right end in fig. 4 is taken as an example) of the second testing pin 34 is used for electrically connecting with the connecting seat 24, and the other end (the left end in fig. 4 is taken as an example) is electrically connected with the testing module 30; and a second antenna 35 for transmitting data in a state of being conducted with the main collector path 20.

Based on the above-mentioned connection relationship between the circuit testing device 3 and the radio frequency circuit 2, the testing process of the present disclosure will be described in detail with reference to fig. 5 to 7. Referring to fig. 5, fig. 5 is a flow chart illustrating a method for testing a radio frequency circuit according to an exemplary embodiment. As shown in fig. 5, the test method may include the steps of:

in step 502, an object to be measured is determined.

In this embodiment, the target to be measured can be determined according to the working states of the main set path and the diversity path; wherein the main set path is used for transmitting and receiving data as a target to be measured, and the diversity path is used for receiving data as a target to be measured.

For example, when testing a radio frequency circuit, the test can be divided into two stages, i.e. factory calibration and factory test. In the calibration stage of the factory, it is determined whether the main diversity path 20 and the diversity path 21 can work normally; in the factory test phase, the parameters related to the performance of the main and

diversity paths

20, 21 are further tested. Then, in the factory calibration stage, when the calibration object is the master set path, the master set path is the target to be measured; and when the calibration object is a diversity path, the diversity path is the target to be measured. In the factory test stage, when the test object is a main set channel (the performance of sending and receiving data by the main set channel is tested), the main set channel is a target to be tested; when the test object is a diversity path (the performance of receiving data by the diversity path is tested), the diversity path is the target to be tested.

In step 504A, when the target to be tested is the main set channel, the switch is switched to the first state.

In step 504B, the switch is switched to the second state when the target to be tested is the diversity path.

Taking the switch 23 as a double-pole double-throw switch (DPDT) as an example, as shown in fig. 6 (part of hardware of the circuit testing apparatus 3 is not shown), the testing socket 22 is between the first antenna 32 and the double-pole double-throw switch 23, the cable socket 24 (i.e. the connecting socket 24) is between the second antenna and the double-pole double-throw switch 23, and the right end of the double-pole double-throw switch 23 can be switched to the main collecting path 20 or the diversity collecting path 21. When the double-pole double-throw switch 23 is in the through state (i.e., the first state), the first antenna 32 is conducted with the main set path 20 to transmit and receive data as the main set antenna, and the test socket 22 is on the main set path; the second antenna 35 is electrically connected to the diversity path 21, and receives data as a diversity antenna, and the cable holder 24 is provided on the diversity path. As shown in fig. 7, when the double pole double throw switch 23 is in the cross state (i.e., the second state), the first antenna 32 is conducted to the diversity path 21, and receives data as a diversity antenna, and the test socket 22 is on the diversity path; the second antenna 35 is in communication with the main-set passage 20 as a main-set antenna for transmitting and receiving data, and a cable is seated on the main-set passage.

Then, when the target to be measured is the main set path, the double pole double throw switch 23 can be switched to the through state. As shown in fig. 6, in the factory calibration phase, when the calibration object is the main set path, the double-pole double-throw switch 23 is switched to the through state (the switching state of the double-pole double-throw switch 23 can be controlled by the control module 33), and then the test socket 22 is electrically connected to the main set path 20, so that the test module 30 can perform accurate main set calibration on the main set path 20. For the factory test stage, when the test object is the main set channel, the double-pole double-throw switch 23 is switched to the through state, then the test socket 22 is electrically connected with the main set channel 20, and the test module 30 can perform accurate main set test on the main set channel 20 through the process of transmitting and receiving data by the first antenna 32. When the target to be measured is a diversity path, the double-pole double-throw switch 23 can be switched to a cross state. As shown in fig. 7, in the factory calibration stage, when the calibration object is a diversity path, the double pole double throw switch 23 is switched to the cross state (the switching state of the double pole double throw switch 23 can be controlled by the control module 33), the test socket 22 is electrically connected to the diversity path 21, and the test module 30 can perform accurate diversity calibration on the diversity path 21. In a factory test stage, when a test object is a diversity path, the double-pole double-throw switch 23 is switched to a cross state, the test socket 22 is electrically connected with the diversity path 21, the cable socket 24 is electrically connected with the main diversity path 20 to maintain the main diversity path 20 in a data transmission state, and the test module 30 can perform an accurate test of diversity reception data on the diversity path 21. It will be appreciated by those skilled in the art that although the cable tray 24 (as a docking tray) is less accurate for testing during the factory testing phase than the test tray, it is only necessary to maintain the main bus path 20 in a data transmitting state. In other words, when the diversity path 21 is tested in the factory test stage, the accuracy requirement on the main diversity path 20 is not high enough to maintain the data connection (it can be understood that the main diversity path 20 can transmit and receive data), and the data reception of the diversity path 21 needs to be accurately tested by the test socket 22. Therefore, in the test scheme of the radio frequency circuit disclosed by the disclosure, the on-off state of the double-pole double-throw switch 23 is controlled and switched, so that the test socket is always connected with a path to be accurately tested, and accurate test is performed. On one hand, the accuracy of testing the main set access and the diversity access by using the test seat can be ensured, on the other hand, the test of the main set access and the diversity access in the radio frequency circuit can be completed only by using the same test seat without arranging corresponding test seats aiming at the main set access and the diversity access respectively, so that the hardware cost is reduced, and the space occupied by the radio frequency circuit is reduced.

In step 506, either the main set path or the diversity path is tested.

In the present embodiment, the step 504A is accepted, and when the switch is switched to the first state, the main set path is tested; in step 504B, the diversity path is tested when the switch is switched to the second state.

The present disclosure also provides an electronic device, which may include the radio frequency circuit in any of the above embodiments, and for the description of the radio frequency circuit in the electronic device, reference may be made to the above embodiments, which are not described herein again.
