Embodiment Construction

[0059] according to Figures 1 to 5 A first embodiment of a high-frequency shielding housing according to the invention for avoiding intermodulation problems is shown, in particular a housing in the form of a filter comprising coaxial resonators. The filter can also be referred to as a coaxial cavity filter, which can in principle be designed as a bandpass filter, notch filter or the like. In the present case, the filter is used, for example, as a duplexer, such as is required in the field of mobile communication technology.

[0060] According to the illustrated embodiment, a coaxial cavity filter 1 , which is sometimes also referred to below only as a cavity filter or coaxial filter 1 , comprises a box-shaped overall housing 2 which faces at least one side ( Here is up) wide open. The open side OS is closed by a cover 17 for the operation of the coaxial filter (see image 3 ). The housing 2 also has a base 5 , a surrounding housing wall 6 and an inner conductor 7 arranged...

Abstract

An improved high-frequency shielded housing is characterized by the following features, among others: multiple contact sections (K; KG; KD) are formed or provided arranged offset to one another between the housing cover (17) and the housing (3), galvanic separating sections (T; TG; TD) are formed or provided between the contact sections (KG; KD), the housing cover (17) and the housing (3) are galvanically separated in the regions of the galvanic separating sections, and screw connections (25) are provided in the contact sections (K; KG; KD), the housing cover (17) and the housing (3) being galvanically contacted in the regions of the screw connections.

Description

technical field [0001] The invention relates to a high-frequency shielding shell, in particular to a high-frequency shielding filter shell. Background technique [0002] In communications technology, for example in radio and television transmission technology and in the field of mobile communications, the isolation of devices, housings, housings, components or generally assemblies with respect to high-frequency radiation is of great importance. For the sake of simplicity, only so-called high-frequency shielded isolation is usually mentioned. As a result, high-frequency radiation is to be prevented from escaping from the area to be insulated (housing, etc.) or entering the area to be insulated (housing, etc.). High-frequency interference radiation is to be avoided bidirectionally by this measure, the effects of which can be varied here. In addition to the incidence of undesired signal components, so-called undesired intermodulation components can also occur. Corresponding ...
