Abstract:
1. A method comprising: attaching a perimeter wall of a cofired feedthrough to an interior wall of a ferrule to form a hermetic seal between the cofired feedthrough and the ferrule, wherein the cofired feedthrough comprises a feedthrough ground conductive via and a feedthrough ground conductive pathway electrically coupled to the feedthrough ground conductive via; electrically coupling the feedthrough ground conductive via to the ferrule; attaching a cofired capacitive filter array to the feedthrough, wherein the cofired capacitive filter array includes a filter array ground conductive pathway and at least two filter array active conductive pathways, wherein the at least two filter array active conductive pathways are capacitively coupled to the filter array ground conductive pathway; and electrically coupling the filter array ground conductive pathway to the feedthrough ground conductive pathway.
