| 摘 要： | 调制器是通信系统中发射机的重要组成部分,可以由此获得调频信号。其中基于锁相环的调制器,所获得调频信号,其载频稳定度很高,可以达到晶体振荡器的频率稳定度。该方法的优点是集成度高且功耗低,所需硬件少。基于国家半导体的锁相环芯片LMX2326,设计了实际应用电路,实现了数字信号的频率调制,得到很好的效果,具有实际的工程意义。

| Abstract: | The modulator is a part of the communication system.We can get FM signal by a modulator which based on PLL.The stabilization of its carry frequency is as high as an oscillator.The advantage is that it can be used to design an actual circuit with fewer device and lower power assumption.This article provides a good method to realize the 2FSK with LMX2326.So you can get some useful information from the paper. |
