Process for metallizing monolithic microwave ceramic filters

摘要

A monolithic microwave ceramic filter has a ceramic body with an outer surface, resonator bores being formed in the ceramic body and defining surfaces within the resonator bores, and coupling voids being formed in the ceramic body between the resonator bores. A process for metallizing the monolithic microwave ceramic filter includes covering at least the coupling voids with ceramic foil, and subsequently galvanically metallizing the ceramic body to produce a metallizing over at least a portion of the outer surface of the ceramic body and the surfaces within the resonator bores.
