Description
Technical Field
The present utility model relates to the field of current control technologies, and in particular, to a communication device and an electronic device thereof.
Background
A Power Amplifier (PA) refers to an Amplifier that can produce maximum Power output to drive a load (e.g., a speaker) under a given distortion rate. The power amplifier plays a role of a pivot for organizing and coordinating in the whole sound system, and the power amplifier dominates whether the whole sound system can provide good tone quality output to a certain extent. The power of the power supply is converted into a current which changes according to an input signal by utilizing the current control function of the triode or the voltage control function of the field effect transistor. Because the sound is waves with different amplitudes and different frequencies, namely alternating current signal current, the collector current of the triode is always beta times of the base current in the amplifying region, and beta is the current amplifying coefficient of the triode. The power amplification is completed through continuous current amplification.
Common power amplifiers include radio frequency power amplifiers, which are an important component of various wireless transmitters. In the front-stage circuit of the transmitter, the power of the radio frequency signal generated by the modulation oscillation circuit is very small, and the radio frequency signal can be fed to an antenna to radiate after a series of amplification-buffer stages, intermediate amplification stages and final power amplification stages are needed to obtain enough radio frequency power. In order to obtain a sufficiently large rf output power, an rf power amplifier must be employed. Radio frequency power amplifiers are an important component of transmitting devices. The main technical indexes of the radio frequency power amplifier are output power and efficiency. In addition, the harmonic components in the output should be as small as possible to avoid interference with other channels. The radio frequency power amplifier has wide application in communication systems in China and can be classified according to different output efficiency and power. When judging the performance of the radio frequency power amplifier, the evaluation indexes mainly related to the performance include gain condition, output power, third-order intermodulation coefficient and the like.

Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
It should be noted that, as shown in fig. 1, fig. 1 is an exemplary diagram of an application scenario of a communication device according to an embodiment of the present utility model. The communication device includes a power amplifier, a transceiver, a duplexer, an antenna, and a power supply VCC.
The transceiver comprises a signal output end 101 and a signal receiving end 102; the power amplifier comprises a signal receiving end 111, a signal transmitting end 112, a power supply end 113, a signal receiving end 114 and a signal transmitting end 115; the duplexer includes a signal receiving terminal 121, a signal transmitting/receiving terminal 122, and a signal transmitting terminal 123. The signal output 101 of the transceiver is connected to the signal receiving 111 of the power amplifier. The signal transmitting end 112 of the power amplifier is connected with the signal receiving end 121 of the duplexer, and the power supply end 113 of the power amplifier is connected with the power supply VCC; the signal transmitting/receiving terminal 123 of the duplexer is connected to an antenna. The transceiver is used for transmitting signals to the power amplifier and receiving signals transmitted by the power amplifier, and the power amplifier is used for amplifying the power of the signals transmitted by the transceiver and transmitting the amplified signals to the antenna through the duplexer. The diplexer is used for receiving the signals sent by the power amplifier, receiving the signals sent by the antenna and isolating the signals sent by the power amplifier from the signals sent by the antenna, so that the two signals can work normally under the condition of sharing one antenna. The power supply is used for supplying power to the power amplifier, so that the power amplifier can work normally.
In the signal transmission working condition, the transceiver sends the transmission signal to the power amplifier through the signal output end 101, and the signal receiving end 111 of the power amplifier amplifies the power of the transmission signal after receiving the transmission signal, so as to obtain an amplified signal. The power amplifier then transmits the amplified signal to the diplexer through signal transmitting terminal 112. The diplexer receives the signal transmitted from the power amplifier through the signal receiving terminal 121, and then transmits the transmission signal to the antenna, and the antenna transmits the signal.
And under the signal receiving working condition, the antenna receives the receiving signals sent by other equipment and sends the receiving signals to the duplexer.
