ABSTRACT:
Pre-fired ceramic substrates are elected according to the desired electrical performance of the filter. If necessary for enhanced performance, the surfaces of the substrate may be lapped to assure that their top and bottom surfaces are parallel and their surface finish is smooth. The top surface of a lower layer is coated with a conductive film using thick film techniques then patterned to define the filter trace pattern. For precise dimensional control, photolithographic techniques may be used. The bottom and the sides of the lower layer are coated with the same conductive film. A seal glass which has a coefficient of thermal expansion which is matched as closely as possible to that of the ceramic substrate is screen printed onto the top surface of the lower layer. The top of the upper layer is screen printed with the conductive film and the bottom of the upper layer is coated with the seal glass. The upper and lower layers are bonded together by clamping them together and firing the seal glass. The sides of the assembly are then coated with a conductive film to provide groundplane connection.
