ABSTRACT:
A directional bridge coupler includes a coaxial balun having a coaxial cable with a plurality of ferrite beads disposed about an outer conductor of the coaxial cable, and a circuit substrate accommodating a directional bridge coupled to an output of the coaxial bridge. A conductive package having an internal cavity houses the circuit substrate and the coaxial balun. A polyiron saddle straddles a portion of the coaxial balun within the internal cavity of the conductive package.
