摘　　要：在电子侦察领域,超宽带多通道接收前端对信道接收机起着至关重要的作用。提出了一种超宽带、多通道、低噪声、低灵敏度、大动态范围接收前端的设计方案。通过设计仿真和实物样机的研制测试,验证了该方案的可行性。与传统方案相比,该接收前端样机噪声系数和开关隔离度各提升20%以上,实物尺寸为53 mm×115 mm×9 mm,指标性能达到设计要求。The microwave receiving front-end plays an important role in a channel receiver in the field of electronic surveillance.This paper presents a design scheme for an ultra-wideband,multi-channel,low-noise,low-sensitivity,and large dynamic range receiving front-end.Design simulation and prototype testing were used to verify the feasibility of the solution.Compared to traditional schemes,this receiving front-end optimizes the noise figure and switching isolation by 20%.The product size is 53 mm×115 mm×9 mm,and the performance indices meet the design requirements.
