Abstract: This paper presents the design, manufacture, integration and measured performance of a redundancy and reconfiguration matrix developed for the transmit section of the EuroSkyWay multimedia satellite. The matrix includes the RF section and the control section with the telemetry/telecommand functions. The EQM equipment includes two functions; a 12‐ for‐10 redundancy switch matrix (RSM) including the possibility to switch each redundant path to any of the outputs and a 3‐to‐9 configuration switch matrix (CSM) including the possibility to switch any input to any output. The used switch is a GaAs MMIC SP3T reflective type. Trade‐offs have been made in order to select the best electrical solution and mechanical structure in terms of minimum losses, high isolation, minimum mass and size, and low cost.
