Classification: CPC H | IPC H

Claim 1:
2. The radio-frequency power amplifier device according to claim 1,
wherein the carrier amplifier semiconductor device or the peak amplifier semiconductor device is a monolithic semiconductor device,
the monolithic semiconductor device includes:
a gate bias circuit that supplies a bias voltage to a gate electrode of a transistor included in an amplifier; and
a gate terminal that is connected to the gate electrode,

the gate bias circuit includes:
an input terminal to which the carrier-amplifier bias power supply voltage or the peak-amplifier bias power supply voltage is supplied; and
an output terminal that outputs the bias voltage from the gate bias circuit,

the radio-frequency power amplifier device further comprises, on the principal surface:
a wiring pattern that is wired in the first wiring layer;
a first connecting wire that connects the output terminal and the wiring pattern; and
a second connecting wire that connects the wiring pattern and the gate terminal, and

the bias voltage is supplied from the output terminal to the gate electrode along a path via the first connecting wire, the wiring pattern, and the second connecting wire in stated order, the path being different from a path of the radio-frequency signal.
