Abstract:
A power amplifier circuit includes an amplifier transistor having a base, a collector, a bias circuit, and a first resistance element connected between the base of the amplifier transistor and the bias circuit. The bias circuit includes a voltage generation circuit, a first transistor having a base to which a first direct-current voltage is supplied, and an emitter from which the bias current or voltage is supplied, a second transistor having a base to which a second direct-current voltage is supplied, and an emitter connected to the emitter of the first transistor, a signal supply circuit disposed between the base of the amplifier transistor and the base of the second transistor, and an impedance circuit disposed between the base of the first transistor and the base of the second transistor.

Claim (Index 8):
The power amplifier circuit according to  claim 5 , wherein:\n the voltage generation circuit comprises a fourth transistor and a fifth transistor that are connected in series, a base or a gate of the fourth transistor is connected to a collector or a drain of the fourth transistor, and the first DC voltage is output from the collector or the drain of the fourth transistor, a base or a gate of the fifth transistor is connected to a collector or a drain of the fifth transistor, and an emitter or a source of the fifth transistor is grounded, and an emitter or a source of the third transistor is connected to the base or the gate of the fifth transistor.
