摘　　要：文中分析并探索了射频信号频谱中出现的近端杂散及其产生的根源,且采取具体方法和技术措施消除或减弱其干扰,从而起到降低数据通信误码率,提高射频系统通信质量的明显效果。The reasons of near-end spurious present in RF signal were analyzed and explored. Some specific methods and techniques were used to eliminate or decrease their interference. These measures can effectively reduce the bit error ratio of data communication and improve the communication quality of RF system.
