Problems solved by technology

This creates a problem of mechanical complexity and requires a larger area for tool (eg nut) access and also introduces the possibility of damage to components during alignment
[0004] The above make the precise configuration and integration of solid dielectric multimode filters problematic and may hinder their application in commercial radio systems

Embodiment Construction

[0052] Examples will be described below. In the following description of embodiments of the present invention, the same reference numerals will be used for the same or equivalent features in different drawings.

[0053] Embodiments described below relate to a bridge for coupling radio frequency resonators, the bridge comprising a solid body of dielectric material. The body can be shaped as an elongated parallelepiped or any other elongated shape capable of coupling the two modes of adjacent resonators.

[0054] Figure 1a and Figure 1b is a simple illustration of parallel resonant modes occurring in adjacent RF resonators.

[0055] The magnetic and electric field morphologies of the parallel modes in adjacent RF resonators 101 can be found in Figure 1a and Figure 1b see in. By coupling energy between two or more resonators 101 in a similar manner, they can be used to form a filter.

Abstract

An iris bridge (100) for coupling two radio frequency resonators is provided. The bridge comprises: a body of dielectric material having an exposed first surface area, predetermined length, width andthickness and having an elongate shape along the length of the body; a hole (202, 302, 402, 502, 602) disposed through the body along the width of the body, the hole (202, 302, 402, 502, 602) having awall (222) forming a second surface area of the body; and a conductive coating covering the exposed first surface area of the body and a first portion of the second surface area of the body. A secondportion (112, 312, 512) of the second surface area is free of conductive coating forming a non-conductive section of the wall (222) of the hole (202, 302, 402, 502, 602). A method for tuning such bridge for coupling radio frequency resonators is also described.

Description

technical field [0001] The present invention relates to the field of radio frequency resonators and methods of tuning radio frequency resonators. Background technique [0002] As radio equipment becomes more compact and integrated, there is a new need to produce low-loss, high-power filters with a small volume or form factor. This is primarily to enable the components to be compactly packaged and used in conjunction with large antenna arrays for multiple input multiple output (MIMO) systems. Prior to final assembly of such radio systems, the filter components need to be configured in the form of frequency and bandwidth calibrations to bring them to the required specifications. [0003] Metallic or dielectric screws have been used to perturb electromagnetic fields for frequency or bandwidth adjustment in various filter types. For example, mechanical or discrete nut and screw components can be used with cavity filters and solid dielectric resonators. The nature of the high ...
