Abstract:
A radio-frequency circuit includes a first switch which includes a common terminal, a first selection terminal, and a second selection terminal, and switches between connecting the common terminal and the first selection terminal and connecting the common terminal and the second selection terminal; a first low-noise amplifier including an input terminal connected to the first selection terminal, and a second low-noise amplifier including an input terminal connected to the second selection terminal. The frequency band in which the first low-noise amplifier amplifies a radio-frequency signal by at least a predetermined gain includes the frequency band in which the second low-noise amplifier amplifies a radio-frequency signal by at least a predetermined gain.
