Abstract
A radio frequency (RF) power amplifier comprises an output stage amplifying circuit and a counterpart waveform generator. The output stage amplifying circuit receives a first waveform through an input node and amplifies the first waveform so as to output an amplified waveform through an output node. The counterpart waveform generator generates a second waveform corresponding to a portion of frequency components of the first waveform. The output stage amplifying circuit and the counterpart waveform generator are electrically coupled such that the second waveform is applied to the input node of the output stage amplifying circuit to substantially compensate the portion of frequency components of the first waveform.
