摘要： A radio communication circuit includes a transmitter that includes a modulator modulates a signal with a first modulation scheme and a power amplifier amplifies the signal modulated with the first modulation scheme and output the amplified signal and transmits the amplified signal, a receiver that includes a demodulator demodulates the signal output from the transmitter with a second modulation scheme that is different from the first modulation scheme, a pre-distortion compensator compensates occurred upon the amplification of the signal, of the signal input to the transmitter, based on the demodulated signal and a power controller controls supply of power to the receiver and the pre-distortion compensator and stop the supply of the power based on an average power level of the signal output from the transmitter and a peak-to-average power ratio that is a ratio of an instantaneous peak power level to the average power level.

摘要： A first signal path has one or a plurality of coils arranged in series, the coils being connected to the output of a first amplifier. A second signal path has the same number of coils as the coils of the first signal path, the coils being arranged in series and connected to the output of a second amplifier. Coupling paths have capacitors and couple the first signal path and the second signal path at both ends of the corresponding coils on the first signal path and the second signal path. A SW controlling unit switches a switch to a contact when a signal is input from the first amplifier and switches the switch to a contact when a signal is input from the second amplifier.
