Abstract:
A multiple-loop microwave frequency synthesizer is provided with an upper and a lower phased-lock loop. The phased-lock loops are mutually connected to a novel sampling mixer and their outputs are connected to an up-converter for providing microwave frequency generated signals. The phased-lock loops are provided with a plurality of programmable frequency dividers connected to a processor controller to provide a wide range of adjustable frequencies up to 20 gigahertz at the output of the frequency synthesizer.
