High-frequency power amplifier
First Claim
1. A high-frequency power amplifier with a temperature compensation function for power amplifying a high-frequency signal, the amplifier comprising:
- a power amplifying transistor having an emitter grounded;
a high power output bias circuit that supplies a high power output current corresponding to a high power output of the high-frequency power amplifier to the power amplifying transistor; and
a low power output bias circuit that supplies a low power output current corresponding to a low power output of the high-frequency power amplifier to the power amplifying transistor.
