摘要: A transmitter comprises a baseband processor, wideband phase modulator and an amplitude modulated amplifier. signal is provided through the processor converted into polar coordinates, comprised of components, with component being transmitted to The amplifier independently controllable current sources, modulator, for modulation upon carrier wave, subsequent transmission amplification according control imposed by sources.
