一种实用的单片机控制射频频率合成系统

A Practical Radio Frequency Synthetic System Controlled by a Single Chip Microcontroller

介绍一种用于国产民用数传电台生产中的频率合成系统,概述了其基本构成,工作原理以及软硬件设计时的一些具体做法,该频率合成系统采用单片微机控制,直接工作在电台的发射频率上,具有稳定度高.频谱纯,成本低,智能化等特点.

In this paper, the authors introduce a frequency synthetic system for applying in the production of the civil transceiver made in our country for digital transmission, and summarize the basic constitution, the working principle, the software and hardware design method of the system. The system is controlled by a single chip microcomputer, directly worked at the transmitting frequency of the transceiver, and has the advantages of a higher instability, a purer spectrum, a lower cost, intellectualization and so on.
