ABSTRACT:
A network having a plurality of network ports includes a plurality of substantially identical independent components, each one thereof having a plurality of ports, the degree of coupling among the ports of each component being characterized by a predetermined scattering coefficient matrix. A plurality of feed networks is included, each one having: a first port corresponding to one of the plurality of network ports; and, a plurality of second ports each one being coupled to a corresponding one of the plurality of ports of each one of the plurality of components, the degree of coupling among the first port and the plurality of second ports of each of the feed networks being characterized by a predetermined scattering coefficient matrix. The plurality of feed networks and the coupling thereof to the components characterize the network with a scattering coefficient matrix, relating the coupling among the network ports, different from the scattering coefficient matrix characterizing each one of the components. The plurality of feed networks and the coupling thereof to the components provide a pair of the network ports with a degree of coupling less than the degree of coupling between the pair of component ports coupled to said pair of network ports. The network may be a reciprocal network, such as a power divider/combiner, in either waveguide or strip transmission line, or a non-reciprocal network, such as a circulator network.
