Classification: CPC H | IPC H

Claim 0:
1. A polar transmitter, comprising:
a transmitter for transmitting a radio frequency signal;
a processor that includes a digital modulation circuit, the 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, the correction circuit configured to:
apply a 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,

wherein the processor is configured to:
provide the corrected amplitude signal component and the corrected phase signal component to the 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.
