    摘要: Embodiments of the present invention disclose a Doherty power amplifying circuit. The Doherty power amplifying circuit includes at least two asymmetrical two-branch power devices, and each of the at least two asymmetrical two-branch power devices includes two power amplifiers; and in the at least two asymmetrical two-branch power devices, one power amplifier included in each asymmetrical two-branch power device separately forms a peak power amplifier of the Doherty power amplifying circuit, and the other power amplifiers included in all the asymmetrical two-branch power devices jointly form a main power amplifier of the Doherty power amplifying circuit. The present invention further correspondingly discloses a power amplifier. The use of the Doherty power amplifying circuit and the power amplifier in the present invention helps improve heat dissipation of the main power amplifier, and reduce the number of devices of a circuit, an area of the circuit, and costs.

    摘要: A Doherty amplifier has a distributor for branching an input signal into two signals, a carrier amplifier to which one of the signals is inputted from the distributor, a peak amplifier to which another signal of the signals is inputted from the distributor, and a synthesizer for synthesizing output signals from the carrier amplifier and the peak amplifier. The carrier amplifier has a compound semiconductor device with at least two terminals. The peak amplifier has a single element semiconductor device. Bias voltages having the same polarity are applied to the two terminals of the compound semiconductor device.
