Problems solved by technology
However, the power amplifier in the mobile terminal usually only uses one transmission gain to transmit signals, and does not pursue the control of transmission power consumption.
With the increasingly stringent power consumption requirements, although there are some methods to achieve power consumption control through the change of the transmission gain, there are problems of relatively extensive adjustment and rigid adjustment point setting.

The invention discloses a radio frequency transceiver device and method and a mobile terminal, which belong to the field of radio frequency transceiver technology. The radio frequency transceiver device includes a receiving unit; a processing unit connected to the receiving unit; The transmission gain and the corresponding preset adjustment voltage; the power amplifier unit is connected to the processing unit; the processing unit extracts the corresponding adjustment voltage according to the calculated transmission gain and outputs it to the power amplifier unit; the power amplifier unit outputs with the corresponding transmission gain according to the adjustment voltage The method includes receiving the wireless signal sent by the outside and obtaining the signal strength; calculating and obtaining the transmission gain required for output; according to the calculated transmission gain, calling and outputting the corresponding adjustment voltage; and then outputting with the corresponding transmission gain. The beneficial effects of the above technical solution are: better control of the transmission power consumption of the mobile terminal; flexible and convenient setting, convenient use, and low implementation cost.
Description
technical field [0001] The present invention relates to the field of radio frequency transceiver technology, in particular to a radio frequency transceiver device and method and a mobile terminal. Background technique [0002] In the existing 3G communication, a power amplifier (Power Amplifier, PA) needs to be used to transmit the signal, so as to avoid signal distortion, thereby reducing the coverage of the signal. With the gradual miniaturization of mobile terminals, the requirements for transmission power consumption will become more and more stringent, so as to increase the standby time of mobile terminals as much as possible. However, the power amplifier in the mobile terminal usually uses only one transmission gain to transmit signals, and does not pursue the control of transmission power consumption. With the increasingly stringent power consumption requirements, although some methods of power consumption control through the change of the transmit gain have emerged,...
