Claim 18:
19. The radio-frequency power amplifier device according to claim 17,
wherein carrier driver amplifier power supply wiring is wired in a lower wiring layer, on which the second monolithic semiconductor device is disposed, of a die pad layer of the multilayer submount substrate, or peak driver amplifier power supply wiring is wired in a lower wiring layer, on which the first monolithic semiconductor device is disposed, of the die pad layer of the multilayer submount substrate, the carrier driver amplifier power supply wiring supplying power to the carrier driver amplifier, the peak driver amplifier power supply wiring supplying power to the peak driver amplifier,
in the plan view of the multilayer submount substrate, the carrier driver amplifier power supply wiring or the peak driver amplifier power supply wiring is disposed to stay within an outer perimeter boundary of the die pad layer in a direction orthogonal to an extension direction of the carrier driver amplifier power supply wiring or the peak driver amplifier power supply wiring.
