Rf-resonator tuning

Abstract

A RF-resonator (1) comprises a resonator body (2) with at least one resonant cavity (3). A conductive sheet material forms a surface area of the resonant cavity (3), the conductive sheet material being deformable by application of a mechanical force for tuning the resonator to a target frequency. A method for tuning the RF-resonator, comprising the following steps: measuring the resonance frequency of the resonant cavity (3), and deforming the conductive sheet material by applying an increasing mechanical force to the conductive sheet material until the target frequency of the resonant cavity (3) is reached.

Description

[0001] The present invention is based on the prior application EP 05 290 294.7 which is hereby incorporated by reference. technical field [0002] The invention relates to a radio frequency resonator comprising a resonator body with at least one resonator cavity and a method for tuning the radio frequency resonator. Background technique [0003] Electronic systems and user access systems using extremely high radio frequency (RF), such as optical data transmission equipment or millimeter-wave radio equipment, point-to-point or point-to-multipoint, and telematics equipment, require resonators with precisely tuned resonator frequencies and filters. [0004] In order to ensure that the original filter element to be fabricated can be tuned to the exact target frequency required, the prior art utilizes specific microwave tuning elements (eg metal screws / dielectric rods). These elements are generally commercially available, but expensive. The gold plating, the choice of special m...

Problems solved by technology

On the other hand, when trying to keep the screw diameter small compared to the wavelength of free space (e.g. 3.5 mm for 85 GHz) with reduced manufacturing tolerances, screw manufacturing costs increase significantly

State-of-the-art components are also increasingly fragile to operate
