Abstract
A RF router for routing n input signals to m destinations, where the router comprises a backplane coupled to a plurality of RF input terminals, a plurality of RF output terminals, a plurality of splitters and a plurality of connectors. The backplane is also coupled to a controller and a plurality of connectors for receiving a plurality of switching matrices. The RF router comprises a plurality of u×v input switch matrices, a plurality of p×q intermediate switch matrices and a plurality of r×s output switch matrices, where at least one of the plurality of u×v input switch matrices, the plurality of p×q intermediate switch matrices and the plurality of r×s output switch matrices are redundant.
