Abstract
A radio frequency signal transceiver includes: a transmission circuit configured to perform power amplification on an input first analog signal, wirelessly transmit the first analog signal after power amplification, and output the first analog signal after power amplification to a pre-distortion circuit; the pre-distortion circuit configured to convert the first analog signal after power amplification into a second analog signal and output the second analog signal, where the second analog signal is used to feedback distortion of the first analog signal to compensate the first analog signal in advance according to the distortion; and a receiving circuit configured to wirelessly receive a third analog signal, and process and output the third analog signal. The radio frequency signal transceiver can improve efficiency in receiving and transmitting a radio frequency signal, reduce a cost of a base station system, and reduce a difficulty in implementing the base station system.
