摘要： A filter and a method of making a filter to remove unwanted frequency harmonics associated with current filters. The filter is made up of resonators, such that the filter resonates a design frequency. Whereby, at least two resonators are coupled together between an input and an output and at least one of the resonators is of a different design from other resonators, such that the resonator of a different design resonates the same design frequency as the other resonators and resonates different higher order harmonic frequencies than the other resonators.

摘要： A new type of dielectric resonator loaded metal cavity filters that are compact and resonate only the desired frequency, along with a method of making such filters. The more compact dielectric resonator loaded metal cavity filter is made by a method of stacking resonator loaded cavities into a filter. A method of making a dielectric resonator filter or duplexer filter which inhibits the undesired higher order harmonics from passing through the filter. Whereby, the method for inhibiting higher order harmonics includes differentiating sizes of the dielectric resonator and metal cavity as compare to other cavities in the filter to prevent the passage of undesired higher order harmonics through the filter.

The present invention also provides methods of improving skirt response for a filter, as well as other response properties of the filter. One way to improve the filter's properties is where at least one of the resonators in a filter is reversed in orientation as compared to the other resonators. Another way is where at least one of the resonators is reversed in orientation electronically by employing electrode coupling on a top and bottom surface of the filter.
