Abstract
One embodiment of the present invention relates to a system that provides a high frequency local oscillator (LO) signal. The system comprises a first LO that generates a first frequency LO signal component, a mixer that generates a difference signal from the first frequency LO signal component and a second frequency LO signal component, and a second LO that generates the second frequency LO signal component that is a harmonic of the difference signal.
