Abstract
An RF power combiner. A plurality of RF inputs connect to a power combiner switch assembly. RF switches connect each input to a common node. A single stub matching circuit connects between the common node and an output node such that an open-ended transmission line stub extends from the output node. An RF output connector feeds an RF output connection from the output node. The stub of the L-match circuit has fixed length or variable length configurations. As a consequence, the impedances at the common and output nodes are more closely matched.
