Abstract
An iris-less combline filter and a method of providing the iris-less combline filter are disclosed. The filter includes a conductive housing, first and second resonators disposed in the housing, and at least one capacitive coupling element disposed between the first and second resonators, wherein there is no decoupling iris between the first and second resonators.
Claims27
A filter comprising:
- a conductive housing;
- first and second resonators disposed in the housing;
- a non-conductive support member for supporting at least one capacitive coupling a element between the first and second resonators, the coupling element disposed without contacting said first and second resonators;
- and
- the at least one capacitive coupling element disposed between the first and second resonators, the support member includes a threaded portion disposed at one end portion thereof and the housing includes a mating threaded portion for accepting the threaded portion of the support member, wherein the position of the capacitive coupling element can be varied with respect to a surface of the housing by varying an amount by which the support member is threaded into the housing;
- wherein there is no decoupling iris between the first and second resonators.

A method of providing a filter, the method comprising the steps of:
- providing a conductive housing;
- disposing first and second resonators in the housing;
- and
- disposing at least one capacitive coupling element between the first and second resonators without contacting said first and second resonators and with no decoupling iris existing between the first and second resonators;
- and
- supporting the capacitive coupling element between the first and second resonators using a non-conductive support member;
- wherein the at least one capacitive coupling element includes a pair of capacitive coupling elements, and the support member includes a pair of holes disposed at one end portion thereof for positioning respectively the pair of capacitive coupling elements therein.

A method of providing a filter, the method comprising the steps of:
- providing a conductive housing;
- disposing first and second resonators in the housing;
- and
- disposing at least one capacitive coupling element between the first and second resonators, no decoupling iris existing between the first and second resonators, the coupling element disposed without contacting said first and second resonators;
- and
- supporting the capacitive coupling element between the first and second resonators using a non-conductive support member, wherein the support member further includes a threaded portion disposed at one end portion thereof and the housing includes a mating threaded portion for accepting the threaded portion of the support member, wherein the position of the capacitive coupling element can be varied with respect to a surface of the housing by varying an amount by which the support member is threaded into the housing.
