Abstract
A high frequency module includes an amplifier circuit, a matching circuit, and a harmonic wave endpoint circuit. The amplifier circuit has an output terminal. The matching circuit is connected to the output terminal of the amplifier circuit, and includes a first inductor. The harmonic wave endpoint circuit connects the output terminal of the amplifier circuit and ground together, and includes a second inductor. The first inductor and the second inductor are arranged so that a magnetic field occurring at the first inductor and a magnetic field occurring at the second inductor are differentially coupled.
