Scalable Ka band switch matrix in compact LTCC package for satellite communication application

An advanced Ka-band (27.5–30 GHz) Solid State Switch Matrix, based on a high order scalability concept and high integration level has been developed under a Contract with the European Space Agency (ESA) for application in satellite communication. A 4×4 module demonstrator has been designed, manufactured and tested, as a building block of switch matrix scalable to very high order, up to 32 inputs × 32 outputs and more. The end goal is to prove the feasibility of an advanced highly integrated, low mass and cost effective Switch Matrix for use in future Ka-band multi-beam payloads for application either in low level redundancy rings or in flexible on-board channel to beam connectivity.
