Abstract
A multi-phase pulse-modulated polar transmitter and a method of generating a pulse-modulated envelope signal carrying modulated RF signal. Multi-phase pulse modulation technique or similar multi-phase pulse modulation techniques are employed in conjunction with a plurality of power amplifiers to enhance the bandwidth of the transmitter and to reduce out-of-band emissions and noises while easily synchronizing the phase and envelope of the input signal.
