Abstract
A radio-frequency circuit includes a first power amplifier that outputs a first transmission signal and a second power amplifier that outputs a second transmission signal having a frequency different from a frequency of the first transmission signal. In a period in which the first transmission signal the second transmission signal are simultaneously outputted, at least one of the first power amplifier or the second power amplifier reduces transmission power of the at least one of the first power amplifier or the second power amplifier to cause a power component of intermodulation distortion superimposed on a transmission signal output from the first power amplifier and the second power amplifier to be less than or equal to a threshold value.
