A radio transmitter front-end for use in a voice data and RF integrated
circuit (IC) includes a phase correction module that produces a phase
adjusted signal in response to a phase modulated signal and at least one
phase correction signal. An amplitude correction module produces an
amplitude adjusted signal in response to an amplitude modulating signal
and an amplitude correction signal. An amplifier amplifies the phase
adjusted signal and amplitude modulates the phase adjusted signal, based
on the amplitude adjusted signal, to produce a polar coordinate transmit
signal. A correction generation module generates the at least one phase
correction signal and the amplitude correction signal, based on the polar
coordinate transmit signal and the phase adjusted signal.
