    Abstract: Embodiments of this application provide a multiband power amplifier circuit and a radio frequency transceiver, to increase a VBW while ensuring linear correction and reducing a circuit loss. The multiband power amplifier circuit includes a first power transistor, a second power transistor, a first matching circuit, a second matching circuit, a third matching circuit, and a combiner. The first power transistor is coupled to a first input end of the combiner via the first matching circuit. The second power transistor is coupled to a second input end of the combiner via the second matching circuit. A first end of the third matching circuit is coupled to an output end of the first power transistor, and a second end of the third matching circuit is coupled to an output end of the second power transistor.

    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.
