An analytical, exact method for the synthesis of multiport microwave networks formed by coupled resonators is proposed. The method is based on the definition of a novel class of coupling matrix with non-resonant nodes and an arbitrary number of input/output ports. The use of this coupling matrix allows a synthesis procedure analogous to the one used for filters. Some applications of the presented technique are the design of power dividers, multiplexers and diplexers. A synthesis example of a diplexer formed by two box-section filters with one transmission zero at a specified frequency for each one is included.
