Claim 7:
8. A method, comprising:
generating, by a digital modulation circuit of a processor in a polar transmitter, a modulated digital signal including an in-phase signal component and a quadrature signal component;
applying, by a correction circuit of the processor, an complex digital offset including an in-phase offset correction factor and a quadrature offset correction factor for generating a corrected amplitude signal component and a corrected phase signal component from the in-phase signal component and the quadrature signal component; and
providing, by the processor, the corrected amplitude signal component and the corrected phase signal component to a transmitter of the polar transmitter,
wherein the transmitter includes an amplifier to combine the corrected amplitude signal component and the corrected phase signal component, and wherein the correction circuit generates the corrected amplitude signal component and the corrected phase signal component to compensate local oscillator feedthrough.
