Abstract
A high frequency power amplifier includes an amplifying device for amplifying an input high frequency signal, a harmonic reflection circuit for reflecting a harmonic outputted from the amplifying device, and a harmonic generating circuit provided at an input terminal of the amplifying device, the harmonic generating circuit including a divider for dividing an input signal of a fundamental wave into two parts, a harmonic generator for generating a second harmonic from one part of the fundamental wave signal, and a combiner for combining the second harmonic generated from the harmonic generator with the other part of the fundamental wave signal to offer a combined signal to the amplifying device, wherein the harmonic reflection circuit reflects the second harmonic.
