摘要
软件无线电技术的不断发展,给短波通信系统设计提供了极大的便利,AD公司推出的高性能上变频器AD9857能够在短波范围内将基带信号直接上变频,实现无中频的直接射频输出。文章所介绍的就是基于这种思想实现的短波通信系统,经实验证明,它能很好地完成系统设计要求的指标。
Design of the shortwave communication system benefits from development of technology of software radio. High performance upconverter AD9857, made by AD Corporation, can upconvert baseband signal of shortwave and achieve radio frequency output without middle frequency, on which the shortwave communication system introduced in this paper is based. Experiment proves that it can fulfill the parameter system wanted.
