Abstract： In order to meet the requirements of complex electromagnetic environment testing and receiver's ultra-wideband, large instantaneous bandwidth, miniaturization and adjustability, this paper designs a receiver RF front-end module with 1.5 GHz~18 GHz ultra-wideband RF signal reception, 1 GHz large instantaneous bandwidth, large dynamic range and ultra-low receiving sensitivity, and it also has the function of outputting intermediate frequency and bandwidth. Through the test, the module is verified and the results meet the design requirements.
Key words : front-end of receiver； ultra-wideband； large instantaneous bandwidth； intermediate frequency； adjustable
