A Doherty amplifier comprising: a distributor that distributes an input signal to each of two paths; a carrier amplifier that receives one signal from the distributor; a peak amplifier that receives the other signal from the distributor; and a combiner that combines output signals from the carrier and peak amplifiers. The carrier amplifier has a compound semiconductor device having two terminals, while the peak amplifier has a single-element semiconductor device. Bias voltages having the same polarity are applied to the respective ones of the two terminals of the compound semiconductor device. |
