Abstract
An intermodulation distortion which is output from a final-stage amplifieris fed back to an inter-stage matching circuitvia a first control circuitand a second control circuit. The first control circuitand the second control circuitcontrol an amplitude and a phase of an intermodulation distortion to be fed back from the final-stage amplifierto the inter-stage matching circuit, such that a synthesized scalar of an intermodulation distortion input from a first-stage amplifierto the final-stage amplifierand amplified by the final-stage amplifierand an intermodulation distortion newly generated by the final-stage amplifieris reduced.
