Abstract
A linear amplifier circuit includes a multi-stage power amplifier that can amplify an input signal to produce an output signal, and a gain feedback control circuit coupled with the output and the input of the multi-stage power amplifier. An adjacent-channel leakage feedback control circuit can detect the output signal at the output of the multi-stage power amplifier and reduce adjacent-channel leakage in the output signal over an output power range based on the detected output signal.
