MULTIBAND POWER AMPLIFIER CIRCUIT AND RADIO FREQUENCY TRANSCEIVER

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.
