Switchable combiner/splitter
 An apparatus for either combining a plurality of high frequency RF signal inputs or splitting a single RF frequency input into a plurality of RF signal outputs employs a switchable combining/splitting section and a switchable matching section. The switchable combining/splitting section operates to either combine the RF signal inputs to a common summed output or to take a matched input and to split it into a plurality of outputs. The matching section operates to switchably match the impedance presented by the combining/splitting section to achieve a minimum or zero insertion loss through the apparatus.
