ABSTRACT:
Microwave power divider/combiners are provided which divide received powers at each of 2.sup.n input ports transmit the divided powers to each of 2.sup.n output ports and combine the transmitted powers at each of the output ports. They have through transmission lines which each couple respective pairs of the input and output ports. In addition, they include shunt transmission lines, an input network of transmission lines which couples the input ports to first ends of the shunt transmission lines and an output network of transmission lines which couples second ends of the shunt transmission lines to the output ports to thereby provide transmission paths from each of the input ports to each of the output ports. The input and output transmission-line networks are configured to be identical and to cause the power divider/combiner to have interport symmetry between the input and output ports and intraport symmetry between any equal sets of input and output ports.
