Design of an Ultra-Wideband and Multi-Channel Receiving Front-End
The microwave receiving front-end plays an important role in a channel receiver in the field of elec-tronic surveillance.This paper presents a design scheme for an ultra-wideband,multi-channel,low-noise,low-sen-sitivity,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.
