Description

A reconfigurable multiplexer solution has been developed that allows flexible re-allocation of channels including contiguous/non-contiguous ones with variable center frequencies and bandwidths. Re-configurable high-Q filters and compensation circuits are directly coupled to a manifold. The novel filter designs are capable to provide remote controlled bandwidth and center frequency tuning of the channel responses with only two actuation drives. This filter solution has been proven by EM designs as well as by measured results of a remote controlled hardware implementation with TE113 dual-mode cavities. The compensation circuits are adapting the adjacent channel impedances when replacing contiguous channels, to avoid complex retuning needs for the channel filters. A 3-channel OMUX design at 11GHz with three re-configurable channel filters and three compensation circuits is introduced to validate the general solution. The application of TE113 dual-mode filters with only 2 actuation drives facilitate compactness, low mass and high reliability of the overall OMUX design. The EM analyses results for the different channel settings, including contiguous/non-contiguous channels with variable center frequencies and bandwidths demonstrate the feasibility of reconfigurable OMUX implementations with state-of-the-art space proven and qualified technologies. Thus, a feasible immediate realization of such multiplexer equipment for satellite missions in the near future will be possible.

Short Speaker Information

Uwe Rosenberg has been working since 1985 in R&D on advanced passive microwave components and subsystem designs (e.g. filters, diplexers, OMUXes, Channel Branching Networks (CBN), antenna feed systems, waveguide subsystems, etc.) for trunk and access radio applications, mobile base stations, large earth stations, airborne, defense and communications and SAR satellite applications.
He was with ANT Nachrichtentechnik (now TESAT Spacecom), Bosch Telecom, Marconi Communications and Ericsson GmbH. For 20 years, he was head of the R&D team for passive subsystem and component developments, which also included later the antenna development.
In 2011, he co-founded together with partners Mician Global Engineering GbR (MGE) where he is Managing Director. MGE provides advanced project, engineering and development services to support new system concepts with novel passive microwave subsystem solutions that are focusing on reliable and high performance/low cost designs while considering implementations with state-of-the-art technologies.

Uwe Rosenberg co-authored the book Waveguide Components for Antenna Feed Systems: Theory and CAD. He has also authored or co-authored over 110 technical papers and has originated more than 50 granted microwave design patents.
