A satellite-borne multi-channel receiver front end of digital beam-forming is presented for the demand of application in complex space environment. The design scheme,realization method and the reliability design are introduced in detail. The test result shows the specification of the developed receiver front end meets the re-quirements,and has characteristics of high degree of integration,compact structure,excellent performance of stabilities among its multiple channels in amplitude and phase. Also the results illustrate that the satellite-borne receiver adopting DBF is a proven technique.
