Patent ID: 8666325

Claim:
A modulator comprising: a radio frequency (RF) component to perform modulation of a baseband signal to produce a modulated RF signal utilizing a magnitude error coefficient and a phase error coefficient, the RF component comprising a feedback receiver to extract the baseband signal, for linear amplification, by producing a magnitude signal plus distortion and a phase signal plus distortion; an algorithm component configured to generate the magnitude error coefficient according to the magnitude signal plus distortion and to generate the phase error coefficient according to the phase signal plus distortion, the magnitude error coefficient and the phase error coefficient collectively comprising an error signal coefficient; wherein the RF component uses the feedback receiver for linear amplification by introducing an inverse magnitude baseband signal at the feedback receiver; and wherein the RF component uses the feedback receiver to produce a limited modulated RF signal by combining the modulated RF signal with an inverse magnitude of the baseband signal, wherein the limited modulated RF signal is used to split the modulated RF signal into phase modulation and amplitude modulation components.
