一种基于DDS和PLL的高分辨率RF频率合成方法

A Method for High Resolution RF-frequency Synthesis Based on DDS and PLL

本文在描述锁相环和直接数字频率合成的原理及优缺点的基础上，介绍了一种基于DDS和PLL的高分辨率RF频率合成方法，分析了仿真和测试结果，为高分辨率RF频率合成器的设计提供了一种思路。

The basic principle and the advantages and disadvantages of PLL and DDS are firstly described in this paper, and then a method for high resolution RF-frequency synthesis is discussed in details. The simulation and test result of the method are analyzed. This paper provides a new train of thought for the design of high resolution RF frequency synthesizer.
