High-frequency power amplifier and communication apparatus

摘要

A temperature compensation circuit 145 included in a collector voltage generation section 130 a applies an offset voltage Vofs(T) to a power control signal Vctrl according to a device temperature. The resulting temperature compensation circuit output voltage Vctrl' (T) is applied to a collector terminal of a bipolar transistor 110 through a voltage regulator 140 and a choke inductor 170.
