  • Power amplifier and impedance adjustment circuit
    Patent number: 11133783
    Abstract: A power amplifier may comprise: an element for amplifying an electrical signal received through an input terminal, and outputting the amplified electrical signal through an output terminal; a first impedance adjustment circuit connected to the input terminal of the element and adjusting impedance with respect to a frequency of a fundamental component at the input terminal; a second impedance adjustment circuit connected to the input terminal of the element and adjusting impedance with respect to a frequency of a multiplied harmonic component at the input terminal; a third impedance adjustment circuit connected to the output terminal of the element and adjusting impedance with respect to the frequency of the fundamental component at the output terminal; a fourth impedance adjustment circuit connected to the output terminal of the element and adjusting impedance with respect to the frequency of the multiplied harmonic component at the output terminal; a first frequency separation circuit which prevents an imped
