Abstract
A microwave integrated circuit is comprised of a ferrite plug in an alumina substrate, fused therein by a glass composition thermally compatible with both plug and substrate, thereby filling any voids at the interface with dielectic material to minimize circuit losses. The method of assembly permits metalizing the substrate after insertion of the plug, minimizing conductive tracking on the substrate, and facilitating alignment of the metalized circuit with the plug.
