Abstract
A radio frequency circuit includes: a first filter having a first passband that corresponds to a portion of a frequency range of a first communication band allocated as a communication band for TDD; a second filter having a second passband that corresponds to a portion of the frequency range of the first communication band, the second passband being different from the first passband; a power amplifier that amplifies a transmission signal in the first communication band; a low-noise amplifier that amplifies a reception signal in the first communication band; and a switch that switches between connecting the first filter and the power amplifier and connecting the first filter and the low-noise amplifier, and switches between connecting the second filter and the power amplifier and connecting the second filter and the low-noise amplifier.
