Claim 1:
2. The power amplifier circuit according to claim 1,
wherein, in a first operation mode, part of the first bias current is supplied to the first terminal of the first transistor via the first resistor, and a remainder of the first bias current is supplied to the first terminal of the second transistor via the third resistor and via the second resistor,
wherein, in a second operation mode, part of the second bias current is supplied to the first terminal of the second transistor via the second resistor, and a remainder of the second bias current is supplied to the first terminal of the first transistor via the third resistor and via the first resistor,
wherein a gain of the power amplifier circuit is lower in the second operation mode than in the first operation mode, and
wherein a second signal obtained by amplifying the first signal is output from the second terminal of the first transistor and from the second terminal of the second transistor.
