Abstract (en)

[origin: EP0718906A1] The filter has a ceramic substrate (1) onto which a pair of stripline resonators (2) are formed. Coupling metal surfaces (3) are electrically isolated (4) on the underside. Metallic pads (5) are formed on the topside with through hole contacts (6). Capacitive coupling between the surfaces (3) on one side and the strip resonators on the other is obtained. The metallic surfaces are produced by photo etching.
