Abstract:
A power amplifier circuit includes a Doherty amplifier including a divider that divides a first signal into a second signal and a third signal, a carrier amplifier that amplifies the second signal and outputs a fourth signal, a peak amplifier that amplifies the third signal and outputs a fifth signal, a combiner that combines the fourth signal and the fifth signal and outputs an amplified signal of the first signal, a first bias circuit that supplies a first bias current or voltage to the carrier amplifier, and a second bias circuit that supplies a second bias current or voltage corresponding to a control signal to the peak amplifier; and a control circuit that supplies the control signal corresponding to a level of the second signal to the second bias circuit. The control circuit includes a detecting unit, an output unit, and a filter circuit.

Claim (Index 7):
