Abstract

A transmitter includes: a modulation circuit for modulating a baseband signal into a multi-bit digital signal containing a radio frequency band component; a plurality of switch mode amplifiers each provided corresponding to a respective bit of the multi-bit digital signal supplied from the modulation circuit; and a signal-synthesizing circuit. The signal-synthesizing circuit connects a band-restricting unit that restricts the band of the output signals of the plurality of switch mode amplifiers and a voltage-current conversion unit that converts output signals of the switch mode amplifiers from voltage into current to perform signal synthesizing.
