摘　　要：对于0.03GHz~6GHz宽带接收机,通常采用模拟变频或零中频技术体制,但是这两种技术体制都各自存在弊端。对此设计了0.03GHz~6GHz高性能射频数字化接收机,去除了模拟变频电路,在数字域内进行变频、滤波、重采样等信号处理后输出宽带基带IQ数字信号。综合分析测试表明,该接收机体积小、成本适中、性能优异,可充分满足各种平台对小型化、低成本、高性能接收机的要求。For 0.03GHz~6GHz broadband receivers,analog frequency conversion or zero intermediate frequency technology system is usually adopted,but both of these two technology systems have theirown disadvantages.In view of these shortcomings,the high-performance RF digital receiver discussed in this paper,without the analog frequency conversion circuit,outputs broadband baseband IQ digital signal after the digital domain frequency conversion,filtering,resampling signal processing.Through comprehensive analysis and testing,the high-performance RF digital receiver is small in size,moderate in cost and excellent in performance,which can fully meet the requirements of various platforms for miniaturization,low-cost and high-performance receiver.
