一种全双工射频收发系统的设计与实现

随着通信技术的进步，射频无线通信的技术取得了迅猛发展，无线通信技术也日趋成熟和稳定，射频收发系统 的通用化和小型化成为一个重要的发展方向。本文对基于软件无线电技术的射频收发原理进行介绍，并对几种常用的方案进 行了分析，对比了各方案集成化、小型化的优缺点，最后使用ADI生产的一款集成式宽带捷变收发器，构建硬件平台，实现一种 简易的全双工多通道的射频收发系统。

Design and Implementation of a Full Duplex RF Transceiver System

With the progress of communication technology, RF wireless communication technology has made the rapid development. Wireless communication technology has become more and more mature and stable. Universal and miniaturization of RF transceiver system have become the important development directions. In this paper, the principle of RF transceiver based on Software Defined Radio technology is introduced, several common schemes are analyzed, and the advantages and disadvantages of the miniaturization and integration of each scheme are compared. Finally an integrated radio frequency (RF) Agile transceiver made by ADI is used to construct the hardware platform and realize a simple full duplex RF transceiver system.
