Abstract:

Along with the development of navigation technology,the electronic equipment requires higher frequency stability,spectrum purity and frequency resolution of frequency source.Besides low noise and high stability,the frequency source shall have high frequency resolution.This article describes a method for realizing a high frequency resolution and low noise frequency synthesizer,which is a good reference for the design of C-band high frequency resolution frequency synthesizer.

Key words: frequency synthesizer;frequency resolution;phase detector;phaselocked loop
