Embodiment Construction

[0038] refer to figure 1 , Figure 2a , Figure 2b , Figure 2c and image 3 , shows a single-mode cavity filter 10, eg according to an example, comprising six rectangular cavities 15 aligned along a linear axis A-A.

[0039] According to other embodiments, the single mode filter comprises three or more rectangular or elliptical cavities without departing from the scope of the claimed invention.

[0040] Preferably, the filter 10 includes a top portion 16 a and a bottom portion 16 b configured to be connected to each other in a known manner so as to form the filter body (filter) 10 .

[0041] The coupling aperture 12 is arranged along the filter 10 in a known manner such that, from left to right, the first coupling aperture 12 is followed by the first cavity 15, the first cavity 15 is followed by the second coupling aperture 12 and the second cavity 15, And so on until the last cavity 15(n) is followed by the last coupling aperture 12(n+1).

[0042] According to a prefer...

Abstract

A single mode cavity filter includes at least three rectangular or elliptical resonant cavities and at least four coupling apertures aligned along a linear axis. The filter is configured to be tuned by an electromechanical device (30). The filter comprises a tuning rod (11) located in each of said cavities and configured, in use, to vary the filter tuning. The tuning rod (11) is first aligned along an arcuate axis, and the electromechanical device (30) is configured to move the tuning rod (11) according to the same depth by a single motor (31) incorporated in said electromechanical device (30).

Description

technical field [0001] The present invention generally relates to a single mode cavity filter for terrestrial and satellite applications. [0002] In particular, the invention relates to single-mode rectangular cavities configured to provide a single resonant mode. [0003] More specifically, the present invention relates to a single-mode filter comprising three or more (n) resonant cavities and four or more (n+1) coupling apertures. Background technique [0004] It is well known that single-mode cavity filters are commonly used in radio link applications. [0005] In particular, it is well known that in the case of special events, such as football or exhibition events, telecommunications companies need to use one or more channels, such as satellite channels, to broadcast online information about the special event by way of television or radio channels. [0006] According to known prior art, the telecommunications company offers to, for example, request one of several chan...
