TRANSMISSION SIGNAL AMPLIFIER CIRCUIT, MOBILE COMMUNICATION TERMINAL, CONTROL METHOD FOR TRANSMISSION SIGNAL AMPLIFIER CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a transmission signal amplifier circuit, which has a plurality of transmission signal amplifier sections and can concurrently amplifies a plurality of transmission signals, capable of achieving a technique for suitably reducing power consumption.;SOLUTION: The transmission signal amplifier circuit 100 is configured so that a control section 60 selects one power amplifier as a low-power consumption target on the basis of an access method for a transmission signal to be amplified by each of power amplifiers 11 and 21 and a low-power consumption implementation apparatus 40 decreases voltages to be applied to the power amplifier as low-power consumption target in the order from a voltage of a battery 30 according to an amplitude of a transmission signal amplified by the power amplifier as low-power consumption target.;COPYRIGHT: (C)2014,JPO&INPIT
