|1. (WO2018220668) POWER AMPLIFIER|
|Applicants:||MITSUBISHI ELECTRIC CORPORATION
The present invention is provided with a distortion compensation circuit (5) that amplifies the amplitude of a differential frequency component which is a component of a frequency difference fd between a first frequency f1 and a second frequency fh which are included in a first amplification signal output by a first amplifier (3), and that shifts the phase of the differential frequency component and applies the amplified and phase-shifted differential frequency component to an output terminal (4a) of a second amplifier (4), wherein a synthesis circuit (13) is configured to synthesize the first amplification signal output by the first amplifier (3) and a signal appearing at the output terminal (4a) of the second amplifier (4).
