中频锁相环路设计

The design of the intermediate frequency phase locked loop

本文简要分析了锁相环路的基本原理,提出一种中频锁相环路的设计方法,并对具体设计电路进行了详细阐述。 此设计方案能够使射频信号始终跟踪本振信号,并保持固定的频差。

this article briefly analyzes the basic principle of phase locked loop, puts forward a kind of design method ofintermediate frequency phase locked loop, and elaborates the design of circuit.This design method can make the radio frequency signaltracking local oscillator signal from beginning to end, and maintain a fixed frequency difference.
