Blind RF carrier feedthrough suppression in a transmitter

A transmitter is provided that corrects for both static and dynamic offsets to minimize carrier feedthrough. A feedback loop permits correction to be performed during normal operation of the transmitter, rather than during a calibration sequence in which the inputs are zeroed. The transmitter includes an adder that subtracts a correction signal from an input signal to produce a corrected signal. A filter filters the corrected signal and a modulator modulates the filtered signal to produce an RF signal. The feedback loop includes a mixer that converts the RF signal to baseband, an A/D converter that converts the baseband signal to a digital signal, which is provided to an FFT, a matched filter that filters the signal from the FFT, a Maximum Seeking Frequency Estimator that determines the maximum signal, and a gain that compensates for the feedback loop and produces the correction signal.
