Abstract:
1. A high-frequency power amplifier for amplifying a high-frequency signal, comprising: a high-frequency signal amplification transistor for amplifying the high-frequency signal; a bias circuit for supplying current to a base electrode of the high-frequency signal amplification transistor; an inductor connected between the high-frequency signal amplification transistor and the bias circuit; and a capacitor connected at one end between the bias circuit and the inductor and grounded at another end, wherein the bias circuit includes: a current supply transistor for supplying current to the high-frequency signal amplification transistor; and a temperature compensation circuit for temperature-compensating the high-frequency signal amplification transistor, the high-frequency power amplifier further comprising a resistor connected between the high-frequency signal amplification transistor and the inductor.
