Planar Multiport Quadrature-Like Power Dividers/Combiners

A new class of planar, multiport power dividers/combiners is presented that is a generalization of the branch-line four-port 3-dB quadrature hybrid. They are suitable for combining an arbitrary number of identical reflection-type or transmission-type devices while maintaining a match at the input port. Experimental results are included for a four-way hybrid power divider/combiner.
