ABSTRACT:
A method and apparatus for generating a self-correcting local oscillation includes processing that begins by generating a synthesized frequency from a reference frequency. The processing then continues by dividing the synthesized frequency by a divider value to produce a divided frequency. The processing continues by generating an auxiliary frequency and mixing the auxiliary frequency with the divided frequency to produce a corrected frequency. The processing then continues by mixing the corrected frequency with the synthesized frequency to produce a local oscillation.
