Radio-frequency power amplification circuit having stabilization circuit

摘要

A radio-frequency power amplification circuit is equipped with a transistor and a stabilization circuit that is provided upstream of the transistor. The stabilization circuit is equipped with a series resistor one end of which is connected to the transistor and the other end of which is connected to an input terminal, a resistance element one end of which is connected to the other end of the series resistor, and a short stub one end of which is connected to the other end of the resistance element 22 and the other end of which is grounded via a capacitance element.
