1. A method, comprising:

  • (a) setting first and second offset adjust signals to initial levels based upon temperature and frequency information for minimizing local oscillator (LO) leakage output from a frequency mixer receiving inphase (I) and quadrature (Q) signals;

    (b) measuring LO leakage during operation of the frequency mixer; and

    (c) adjusting the first and second offset adjust signals to minimize the LO leakage output.
