Abstract
A Doherty power amplifying circuit includes at least two asymmetrical two-branch power devices. Each of the asymmetrical two-branch power devices includes two power amplifiers. 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.
