Abstract
An apparatus includes: a transistor including an input terminal for an input signal and an output terminal for an output signal; a matching circuit configured to match a load impedance regarding a fundamental harmonic of at least one of the input signal and the output signal to an impedance of the transistor and include a first conductive film being laminated over the transistor and coupled to at least one of the input terminal and the output terminal; and a processing circuit configured to adjust an impedance regarding a harmonic of at least one of the input signal and the output signal and include a second conductive film being laminated over the first conductive film and coupled to at least one of the input terminal and the output terminal through a via which penetrates through a dielectric layer sandwiched between the first conductive film and the second conductive film.
