発明の名称 (英語) TRANSMISSION CIRCUIT
発明の概要(英語) The disclosed transmission circuit includes: a .SIGMA.-.DELTA. modulator which performs .SIGMA.-.DELTA. modulation on the amplitude-modulation component of a modulating signal and outputs a pulse-width modulated signal; an angle modulator which generates an angle-modulation component signal indicating the angle-modulation component of a signal obtained by multiplying said modulating signal by a transmission output control coefficient corresponding to the transmission output of the power amplifier; and a multiplier which multiplies the pulse-width modulated signal and the angle-modulation component signal and outputs the multiplication result as the output signal to the power amplifier.
