Abstract
A filter assembly (300) with a plurality of cavities serving as said waveguide resonators is presented. The cavities are arranged at least on two levels (x1, y1; x2, y2) of said filter assembly (300). Two or three molded filter parts (301, 302, 303) define the cavities, when the filter parts (301, 302, 303) are assembled. A first opening in a wall between a first and a second of cavity is provided. Said opening serves as capacitive junction between said first cavity and said second cavity. A second opening is provided in another wall between a third cavity and a fourth cavity, said opening serving as inductive junction. The filter parts (301, 302, 303) are at least partially covered by a metal layer.
