Abstract
A variable frequency multiplier circuit for frequency multiplying an input signal provided by an ultra-low phase noise signal source includes a tone generator configured to generate a multiple tones from the input signal; a signal separating circuit configured to separate the multiple tones into tones of interest and idler tones, where the tones of interest are separated into one or more groups and outputted from the signal separating circuit, and the idler tones are terminated; an amplification circuit configured to amplify each group of the tones of interest to optimize small and large signal responses; and a switched filter bank configured to selectively connect a selected tone from the tones of interest to a circuit output.
