A radio-frequency circuit includes: a first transfer circuit that outputs a B1 or B3 first transmission signal amplified by a first power amplifier from a first input/output terminal; a second transfer circuit that outputs an n77 or n79 second transmission signal amplified by a second power amplifier from a second input/output terminal; and a switch. When a B1 first transmission signal and an n77 second transmission signal are simultaneously transmitted, the switch connects the first transfer circuit to a first antenna and connects the second transfer circuit to a second antenna since intermodulation distortion IMD2 overlaps with B1. When a B3 first transmission signal and an n79 second transmission signal are simultaneously transmitted, the switch connects both of the first transfer circuit and the second transfer circuit to the first antenna since intermodulation distortion IMD2 does not overlap with B3.
