On Optimization of a Frequency Discriminator for a Low Phase Noise Microwave Oscillator With Combined Stabilization

Dmitry P. Tsarapkin

Abstract:	This paper describes and solves partly a contradiction between transfer efficiency and bandwidth arising during design of a frequency discriminator (FD) for a modern ultra-low phase noise microwave source equipped with an automatic frequency control (AFC) and a whispering gallery resonator (WGR). Using of the guided WGR resonant modes splitting is proposed as a tool to solve the problem. Some typical situations are analyzed with a help of suitable figures of merit and available FD bandwidth improvements are estimated.
