Abstract: A power amplifier circuit includes: a first branch, including a first amplifier and a first matching network cascaded; a second branch, including a second amplifier and a second matching network cascaded, where a first coupled line enables the first branch and the second branch to form a first combiner; a third branch, including a third amplifier and a third matching network cascaded; and a fourth branch, including a fourth amplifier and a fourth matching network cascaded, where a second coupled line enables the third branch and the fourth branch to form a second combiner. A first output end of the first coupled line is a signal output end of the circuit, and a second output end of the first coupled line is connected to a first output end of the second coupled line, to enable the first combiner and the second combiner to form a series combiner.

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.

Abstract: The present disclosure discloses example transmission/reception separation circuits and transceiver. One example transmission/reception separation circuit includes a transmission amplification circuit, an impedance adjustment circuit, and a reception amplification circuit. An output end of the transmission amplification circuit is connected to the impedance adjustment circuit. The impedance adjustment circuit is further connected to an input end of the reception amplification circuit. The second end of the impedance adjustment circuit and the input end of the reception amplification circuit are further configured to be connected to an antenna. The transmission amplification circuit amplifies a first signal to be transmitted. The reception amplification circuit amplifies a second signal received. When the antenna transmits the amplified first signal, a first impedance is in a high impedance state. The impedance adjustment circuit adjusts a second impedance to a high impedance state when the antenna receives the second signal.
