An RF power combiner (10). A plurality of RF inputs (13, 14, 15, 16) connect to a power combiner switch assembly (21). RF switches (33, 34, 35, 36) connect each input to a common node (31). A single stub matching circuit (41, 42) connects between the common node (31) and an output node (32) such that an open-ended transmission line stub (41) extends from the output node (32). An RF output connector feeds an RF output connection from the output node (32). The stub (41) of the L-match circuit has fixed length or variable length configurations. As a consequence, the impedances at the common (31) and output (32) nodes are more closely matched. |
