Abstract: This application discloses a radio frequency transceiver, and a communication device. A radio frequency amplification circuit includes two transmission paths disposed between a radio frequency input end and a radio frequency output end. The two transmission paths include a first transmission path and a second transmission path. The first transmission path includes a first amplifier, a first coil, a second coil, and a second amplifier that are sequentially coupled. The second transmission path includes a third amplifier, a third coil, a fourth coil, and a fourth amplifier that are sequentially coupled. Any two coils of the first coil, the second coil, the third coil, and the fourth coil are magnetically coupled. The first amplifier and the second amplifier is adjustable, or The third amplifier and the fourth amplifier is adjustable.

Abstract: A matching circuit, a radio frequency front-end circuit, a radio transceiver apparatus, and an electronic device are provided. The radio frequency front-end circuit includes a low noise amplifier and a power amplifier each coupled to an antenna through a matching circuit. The matching circuit includes a transformer, a capacitor, a first switch, and a first inductor element. The transformer is coupled to the power amplifier and the antenna. The capacitor is coupled to the transformer and to the low noise amplifier. The first switch is coupled to the capacitor and to the transformer and is grounded. The first inductor element is coupled to the capacitor and to the first switch and is grounded. A resonant network formed by the first inductor element and the first switch enables the radio frequency front-end circuit to in a wide frequency band.
