Filterorgan mit verteiltem Element und Herstellungsverfahren

摘要

A distributed element filter member comprises a semi-conductor member (12) having a composite dielectric layer (24) disposed on and secured to a first major surface of the member (12), the layer (24) being comprised of a polymerized dielectric material made of either barium titanate or strontium titanate particles in various ranges of mixture; a conductive layer (34) is disposed on portions of the dielectric layer defining an outer ground conductor and an inner conductive layer (36) is disposed on a second major surface of the semi-conductor member defining a signal conductor. The polymer utilized may be selected from an aqueous solution containing acrylic styrene as a copolymer or a solid polyester dissolved in carbitol acetate, or a solid bisphenol A-based epoxy resin dissolved in butyl carbitol acetate with various mixtures of barium or strontium titanate utilized. A filter (12') embodiment includes three layers of polymerized material.
