This work presents theoretical and practical principles allowing to flexibly reconfigure the frequency plan of an output multiplexer. Particularly, based on the investigations performed in this work for the first time it is possible to realize manifold-based multiplexers with multiple channels which can be reconfigured in orbit for both center frequency and bandwidth during the life-time of the satellite.Technology: general issuesbicsscBandbreitebandwidtheinstellbarfilterFiltermultiplexerMultiplexerreconfigurablesatellite communicationSatellitenkommunikationTechnology: general issuesArnold Christianauth1227258BOOK9910346721203321Im Orbit einstellbare Ausgangsfilter und -multiplexer3022275UNINA
