Symmetric N×N branch-line hybrid power divider/combiner

The present invention relates generally to passive microwave devices, and more particularly, to a symmetric N×N branch-line hybrid power divider/combiner. A symmetric N×N branch-line hybrid power divider/combiner has N input ports and N output ports. The divider/combiner divides received powers at each input port and transmits and combines the divided powers to the output ports. The divider/combiner includes N through transmission lines, each coupling a respective input port to a respective output port. The divider/combiner also includes N input branch transmission lines, each coupling a respective input port to a central input node and N output branch transmission lines, each coupling a respective output port to a central output node.
