Abstract

1416166 Filters ELECTRONIC COMPONENTS Ltd AB 21 Feb 1973 [1 March 1972] 9612/72 Heading H1W Resonant circuits 1 are coupled by a common ground plane 3. The circuits are formed by printing a conductive pattern on one side only of a substrate of, e.g. alumina. The coupling may be adjusted by removing a portion 4 of the common ground plane 3. The removed area 4 may extend to the edge of the substrate.
