摘要：A digital wireless transmitter and a method of transmitting a high-powermodulated RF signal using a digital wireless transmitter are provided. In one

embodiment, the transmitter includes: a digital system-on-a-chip configured to receive a

complex digital input signal and having: an all-digital phase-locked loop and digital pulsemodulator configured to modulate a phase and frequency modulation signal based onthe complex digital input signal to yield a modulated complex signal, a driver configuredto generate a pulse-position-modulated and pulse-width-modulated pulse train basedon an instantaneous phase and amplitude of the modulated complex signal and a powersupply modulation control block configured to develop an amplitude modulation controlsignal based on the complex digital input signal that defines a non-constant-envelope foran output signal of the transmitter.
