摘要
本文简要说明了锁相环的构成和基本原理,分析了锁相环中的噪声来源,给出了环路带宽的优化方法。论文结合信号源整机调试实例,提出并实现了一种相位噪声临界时的解决办法。
The paper introduces working theory and performance of PLL, analyze the phase noise source, and give the excellent method of the loop bandwidth.Combines the adjust example of the RF Synthesized Signal Generator, the paper put forward and carry out a kind of method to solve the critical phase noise.
