Abstract:
1. A filter comprising: a block defined by top, bottom and side surfaces wherein said side and bottom surfaces are substantially covered with a conductive material and said top surface defines opposed longitudinal peripheral edges and opposed peripheral side edges; a plurality of spaced-apart through-holes extending between the top and bottom surfaces of said block and defining a plurality of spaced-apart apertures in the top surface, said through-holes including corresponding interior surfaces covered by said conductive material; a plurality of plates comprised of said conductive material and surrounding a plurality of said respective apertures for coupling said respective through-holes to each other and said conductive material on the side surfaces of said block; at least one of said plates in combination with said one of said through-holes associated therewith defining at least a first shunt zero and at least another of said plates in combination with another of said through-holes associated therewith defining at least a second shunt zero; at least a first input/output pad located adjacent one of said side peripheral edges and coupled to said through-hole of said at least firstshunt zero, said through-holes defining said at least first and second shunt zeros being located on said block between said at least first input/output pad and said one of said side peripheral edges; and a coupling bar extending between said at least first input/output pad and said plate of said second shunt zero for coupling said through-hole of said second shunt zero to said at least first input/output pad, said at least first input/output pad and said coupling bar each defining a finger and a slot respectively, said finger on said coupling bar extending into said slot in said at least first input/output pad and said finger on said input/output pad extending into said slot in said coupling bar.
