Abstract
Techniques for reducing harmonics of a local oscillator (LO) signal. A methodology implementing the techniques according to an embodiment includes splitting an LO signal into first and second LO signals using a passive splitting circuit. The method also includes generating one of either a first enable signal or a second enable signal based on the LO signal frequency. The method further includes amplifying and filtering the first LO signal to generate a first band LO signal, in response to the first enable signal, and amplifying and filtering the second LO signal to generate a second band LO signal, in response to the second enable signal. The method further includes combining, using a passive Wilkinson combiner, output paths of the first band processing circuit and the second band processing circuit to provide either the first band LO signal or the second band LO signal as a reduced harmonic LO signal.
