Title:
AMPLIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/146850
Kind Code:
A1
Abstract:
The present invention is provided with: an amplifier that amplifies a signal that has a fundamental frequency within a prescribed frequency band; an input harmonic processing circuit that is connected to the input side of the amplifier and performs input-side impedance matching at the harmonic frequency of the signal; and an output harmonic processing circuit that is connected to the output side of the amplifier and performs output-side impedance matching at the harmonic frequency of the signal. The input harmonic processing circuit is set so that impedance is matched at the harmonic frequency when the fundamental frequency is a first frequency; the output harmonic processing circuit is set so that impedance is matched at the harmonic frequency when the fundamental frequency is a second frequency; and the first frequency and the second frequency are mutually differing frequencies.
