摘要:

随着导航技术的发展,机载电子设备对频率源的频率稳定度、频谱纯度和频率分辨率均提出了更高的要求,除了频率源具有低噪声、高稳定度外,还要求具有较高的频率分辨率。文中提出了一种高分辨率、低噪声频率合成器的实现方法,为C波段高分辨率频率合成器的设计提供了良好的思路。

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
