PURPOSE: A switching power combiner is provided to be capable of matching impedance although a signal path number is varied. CONSTITUTION: The first to nth connection units(S11,S12,S13) selectively connect corresponding ones of N input ports(PI1,PI2,PI3) to a combination node(62). One end of a matching line(63) is coupled with the combination node. A transmission line(64) connects an output port to the other end of the matching line via the (N-1)th to first middle nodes which are arranged sequentially. The first to (N-1)th stubs(66,68) are selectively connected to the first to (N-1)th middle nodes, respectively. The ith stub(i=1, ..., N-1) is connected to the ith middle node when i ones of N input ports are connected to the combination node.
