| Abstract: |
| A satellite-borne multi-channel receiver front end of digital beam-forming is
presented for the demand of application in complex space environment. The desig
n scheme, realization method and the reliability design
are introduced in detail. The test result shows the specification of the develo
ped receiver front end meets the requirements, and has characteristics of high d
egree of integration, compact structure, excellent performance of stabilities am
ong its multiple channels in amplitude and phase. Also the results illustrate th
at the satellite-borne receiver adopting DBF is a proven technique. |
| Key words: active phased array antenna satellite-borne digital beam-forming receiver front end module consistency in amplitude and phase reliability design |
