MMIC SSB frequency translators with image-rejection for satellite transponder applications

Abstract

A highly integrated design for advanced monolithic single side-band frequency translators are presented in this paper. Two monolithic chips have been realised which exhibit between 18-45 dB of upper side-band rejection over C, X, and Ku-band. The chips are designed for small band-to-band frequency translations (such as uplink to downlink) in satellite communications transponders. Since the chips exhibit a wide-band response, image-rejection is also obtained for both chips.<>
