Multi-port, multi-frequency microwave combiner with overmoded square waveguide section

摘要: A multi-port, multi-frequency combiner comprising a main waveguide having cross-section in the shape of right-angle parallelogram and dimensioned to simultaneously propagate co-polarized signals different frequency bands at least one signal that is orthogonally polarized with respect signals, portion being overmoded; plurality junctions spaced along length for coupling selected out waveguide, located an overmoded each unbalanced or pseudo-balanced feed only single side-arm transmitting receiving signals; filtering means disposed within operatively associated junction therein highest band, (1) stopband characteristic band between connected thereto, (2) passband passing lower past junction. In preferred embodiment invention, has section square single-moded rectangular cross-section, singlemoded sections joined by transition side wall which tapered effect from cross-section.
