The broadband Class-J power amplifier using IMFET

摘要

By applying IMFET (Internal Matched FET) technology that implements an impedance matching circuit inside a metal package, a Class-J power amplifier is provided that is miniaturized and has broadband characteristics. The power amplifier according to the present invention is integrated with an amplifying circuit for amplifying an input signal and an amplifying circuit, and the first matching circuit for impedance matching of the second harmonic frequency output from the amplifying circuit and the operating frequency band output from the amplifying circuit. And a second matching circuit for impedance matching.
