Abstract: The present invention relates to an improved and compact filter arrangement and a method for a cost-efficient assembling of such an arrangement. The filter arrangement according to the present invention comprises a cover of the filter chassis that serves both as a mechanical and electrical shielding of the filter chassis and as a carrier of a printed circuit board for electrical components such that the filter chassis and the printed circuit board can refer to the same ground. It is possible to mount additional circuit boards, that are each shielded from each other, from the same direction on said first printed circuit board. The various units are automatically contacted during manufacturing by means of coupling components that connect adjacent units to each other.

Abstract: The present invention relates to a single-piece center conductor (15) for a LC-filter, and a LC-filter comprising at least one such center conductor. The center conductor comprises a first end section (20) with axially form confining fixing means and a second end section with means for direct connection to connecting means of a connector. A general object of the present invention is to provide an improved apparatus for connecting a LC-filter with a connector in terms of intermodulation interference, contact area with the LC-filter, accurate fastening to the LC-filter, assembly time, manufacturing, storage costs and logistics costs.

Abstract: The present invention relates to a cavity filter (20) that includes a plurality of centre conductors which are mounted on an elevation (22) that extends along several cavities. The elevation can be produced on the bottom surface (23) of the cavity body (21) to a high degree of flatness in one single working step, and a precise measurement and precise parallelity between said bottom surface and the side walls (25) of the cavities can be obtained.
