Problems solved by technology
[0003] However, when the distance between the receiving end of the radio frequency signal and the sending end of the radio frequency signal is relatively close, the sending end also sends a relatively high-power radio frequency signal to the receiving end, so that the signal strength received by the receiving end is relatively large, far exceeding the receiving end. The terminal needs to receive the signal, thus wasting the power consumption of the transmitting terminal

The embodiment of the invention discloses a radio frequency signal processing circuit with multiple working modes and a radio frequency front-end unit, which are applied to a sending end. The circuitcomprises a control module used for controlling a first switch and a third switch to be switched off and controlling a second switch to be switched on under the condition that a signal parameter of aradio frequency signal received by a receiving end is smaller than a first threshold value; the radio frequency signal input into the radio frequency signal processing circuit is amplified for the first time by the driving module, amplified for the second time by the power amplification module and then output; the control module is used for controlling the first switch and the third switch to be switched on and controlling the second switch to be switched off under the condition that the signal parameter of the radio frequency signal received by the receiving end is not smaller than the firstthreshold value; and thus, the radio frequency signal input into the radio frequency signal processing circuit is output from the first capacitor, amplified by the power amplification module and thenoutput.
Description
Technical field [0001] This application relates to the field of radio frequency technology, and in particular to a radio frequency signal processing circuit and radio frequency front-end unit with multiple working modes. Background technique [0002] In the communication system, due to the relatively long distance between the receiving end of the radio frequency signal and the transmitting end of the radio frequency signal, the poor channel status, etc., the signal strength received by the receiving end is relatively small, so that the receiving end cannot reach the received signal. demand. At this time, the transmitting end needs to send a higher power radio frequency signal to the receiving end to meet the requirements of the receiving end for receiving signals. [0003] However, when the distance between the receiving end of the radio frequency signal and the transmitting end of the radio frequency signal is relatively close, the transmitting end also sends a higher-power radio...
