Abstract
A frequency synthesizer is built using a phase locked loop incorporating a single side band mixer in the input. The single side band mixer is preferably realized with digital logic and FETs, and the resulting frequency synthesizer simultaneously improves control over the frequency resolution, noise floor and operating frequency range.
