无线寻呼系统中频率合成器的设计

为得到频率稳定度高，频谱纯净的特定频率信号，采用单片机Ｉｎｔｅｌ８０３１对大规模集成锁相环频率合成器ＭＣ１４５１２进行控制，可获得合乎质量要求的频率信号，且设计出的频率合成器具有可靠性高，成本低，体积小，使用灵活方便的特点，文中通过一个具体实例从技术指标，方案选择，工作原理及实施等几方面介绍了这种频率合成器的设计方法。

Frequency Synthesizer Design in Radio-paging System

To generate signals with steady and pure frequency, the single chip microcomputer Intel 8031 is used to control the large scale integrated circuit phase locked frequency synthesizers MC145152. Thus the signal up to the quality requirement is obtained, and the frequency synthesizer can be designed which has the characteristics such as high reliability, low cost, small size and good flexibility. Here is given an example for frequency synthesizer's design methods, including technical parameter, scheme selecting, mechanism and implementation.
