Title:
HIGH-FREQUENCY AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2017/208328
Kind Code:
A1
Abstract:
A high-frequency amplifier is configured such that a second harmonic processing circuit (8) that is a resonant circuit that resonates at a second harmonic of a high-frequency signal includes: an overlying electrode (9) of which one end is connected to a gate electrode (2) of an FET (1) and which has two or more bend sections (9a); a underlying electrode (10) having one end that is grounded; and a dielectric member (11) arranged between the overlying electrode (9) and the underlying electrode (10). This makes it possible to reduce circuit size, and expand the frequency band in which a high-efficiency operation can be expected.
