Claim 14:
15. A system, comprising:
a polar transmitter formed on a substrate; and
a processor formed on the substrate and providing a corrected amplitude signal component and a corrected phase signal component to the polar transmitter, the processor including:
a digital modulation circuit configured to generate a modulated digital signal including an in-phase signal component and a quadrature signal component, and
a correction circuit configured to apply an complex digital offset including an in-phase offset correction factor and a quadrature offset correction factor for generating the corrected amplitude signal component and the corrected phase signal component from the in-phase signal component and the quadrature signal component,
wherein the polar 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.
