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 1):
A power amplifier circuit comprising:\n an amplifier transistor configured to amplify an input signal and output an amplified signal, wherein the input signal is supplied to a base or a gate of the amplifier transistor and the amplified signal is output from a collector or a drain of the amplifier transistor; a bias circuit configured to supply a bias current or a bias voltage to the base or the gate of the amplifier transistor, the bias circuit comprising:\n a voltage generation circuit configured to generate a first direct-current (DC) voltage, \n a first transistor, wherein the first DC voltage is supplied to a base or a gate of the first transistor, \n a second transistor, wherein a second DC voltage is supplied to a base or a gate of the second transistor and an emitter or a source of the second transistor is connected to an emitter or a source of the first transistor, and \n a signal supply circuit disposed between the base or the gate of the amplifier transistor and the base or the gate of the second transistor, the signal supply circuit being configured to supply the input signal to the base or the gate of the second transistor, and \n a first resistance element connected in series between the base or the gate of the amplifier transistor and the bias circuit, wherein the bias current or the bias voltage is supplied to the base or the gate of the amplifier transistor from the emitter or the source of the first transistor via the first resistance element.
