<p>A switchable power combiner which ensures the impedance matching characteristics regardless of the change in the number of signal combining paths. The switchable power combiner receives a plurality of input signals through a plurality of input ports and combines the receives the signal to output the combined signal through an output port. First switching means (30) is arranged between the plurality of input ports and a combing node (40) to connect at least one of the input ports to the combining node. A plurality of impedance matching circuits (50, 52, 54) are selectively activated by second switching means (60) to electrically connect the combining node (40) to the output port (PO).</p> |
