Abstract
A gain compression compensation circuit of a radio frequency power amplifier includes: a low-pass filtering module configured to receive a part of radio frequency signals output from a first power amplification transistor and to filter, from the part of radio frequency signals, radio frequency signals with a frequency above a fundamental wave to obtain a filtered signal; and a rectifying module configured to receive the filtered signal output by the low-pass filtering module and to rectify the filtered signal to obtain a rectified current; and to output the rectified current to a bias transistor and superimpose the rectified current with a bias current Ito flow into the bias transistor.
