Title:
HIGH-FREQUENCY AMPLIFIER AND AMPLIFIER MODULE
Document Type and Number:
WIPO Patent Application WO/2017/122271
Kind Code:
A1
Abstract:
A high-frequency amplifier is provided with: a harmonic supply circuit (3) that blocks passage of a fundamental included in an RF signal amplified by a preceding-stage transistor (1) and supplies a harmonic included in the RF signal to a subsequent-stage transistor (2); and a fundamental supply circuit (4) that blocks passage of the harmonic included in the RF signal amplified by the preceding-stage transistor (1) and supplies the fundamental included in the RF signal to the subsequent-stage transistor (2). As a result, when the subsequent-stage transistor (2) amplifies the RF signal, the harmonic included in the RF signal amplified by the preceding-stage transistor (1) can be used.
