摘要

本文描述并部分解决了现代超低相位噪声微波源的自动频率控制(AFC)和窃语廊谐振器(WGR)在设计鉴频器(FD)时出现的传输效率和带宽之间的矛盾。提出了一种利用波导WGR谐振模式分裂的方法来解决这一问题。利用合适的优值对一些典型情况进行了分析，并对可用的FD带宽改进进行了估计

On optimization of a frequency discriminator for a low phase noise microwave oscillator with combined stabilization

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
