摘要
射频发射机是通信系统中的一种必不可少的设备。本文设计了一种包括数字基带电路和发射电路的数字射频发射机。数字基带电路主要是使用DSP芯片来实现,通过对DSP的编程来实现数据信号的封装与编码;数字基带电路能提供方便的用户接口以实现与上位机的通信,以及组网等功能。发射电路是采用射频测试平台技术来实现,使用模块化的结构设计。在ADS软件环境下对数字射频发射机的电路进行了仿真,仿真结果说明本文的数字射频发射机的设计是有效和可行的。
The RF transmitter is essential equipment in communication system. The digital RF transmitter consists of digital baseband circuit and emission circuit. In this paper, the digital baseband circuit is realized based on FPGA and DSP（digital signal processing）, the data is packaged and coded by the programming of DSP. The digital baseband circuit can implement the communications with computer and networks by user interfaces. The emission circuit is designed by the radio t^equency testing platform. The RF transmitter being designed in this paper is simulated under ADS software environment. The simulation results show that the design method of the RF transmitter provides is effective and feasible.
