摘要：
Disclosed is a distortion compensating and power amplifying apparatus including: a transistor to power amplifies an input signal; a branch circuit to branch the input signal into two signals; distortion compensation means for generating a second harmonic of a fundamental wave for one of branched signals and adding the generated second harmonic to the other branch signal from said branch circuit for input to an input terminal of said transistor; and a termination circuit connected to an output terminal of said transistor and grounding the second harmonic.
