摘要
随着电子技术的飞速的发展,对作为接收机核心部件的频率合成器的性能指标提出了更高的要求,特别是相位噪声指标。锁相式频率合成器作为现代频率合成器的主流,研究其低相位噪声合成技术是很有必要的。简单介绍了频率合成器的组成和工作原理,通过详细分析相位噪声及环路噪声出现的原因,给出了消除噪声的方法。
With the development of electronic technology,the requirement for higher performance of synthesizers being the core component of receiver is put forward,especially the low phase noise performance.It is necessary to study the systhesis technology of low plase noise,as the PLL frequency synthesizer is the main force of modern synthesizer.This article explains the composition and work principle of frequency synthesizer,analyzes the causes of phase noise and circle noise in frequency synthesizer and gives the method of how to eliminate them.
