FABRICATION OF SURFACE MOUNT MICROSTRIP CIRCULATORS USING A FERRITE AND CERAMIC DIELECTRIC ASSEMBLY SUBSTRATE

A method of forming an integrated microstrip circulator includes translating a ferrite disc into an aperture in a dielectric substrate, securing the ferrite disc in the dielectric substrate with an adhesive to form a composite structure, and forming circuitry on an upper surface of the composite str...

Zusammenfassung:A method of forming an integrated microstrip circulator includes translating a ferrite disc into an aperture in a dielectric substrate, securing the ferrite disc in the dielectric substrate with an adhesive to form a composite structure, and forming circuitry on an upper surface of the composite structure and forming surface mount contacts on a lower surface of the composite structure by metallizing the upper and lower surfaces of the composite structure.
