Definitions

  • the invention relates to radio frequency resonators and, particularly, ceramic resonators.
  • Ceramic resonators are widely used to form radio frequency (RF) filters for radio transmitters and radio receivers. Such ceramic filters are typically made of ceramic material that provides a piezo-electric effect and resonates at one or more frequencies.
  • a dual-mode ceramic resonator may resonate at two resonating frequencies, and a triple-mode ceramic resonator may resonate at three resonating frequencies.
  • the ceramic resonators may be combined to each other to form a ceramic filter having desired pass-band characteristics.
  • US 5 812 036 discloses a filter comprising a plurality resonator stages between sequentially coupled between input and output ports.
  • the resonator stages are arranged such that at least one non-sequential pair of stages are physically adjacent.
  • the non-sequential pair of resonator stages are separated by a common internal wall, which defines a bypass coupling aperture therebetween.
  • attenuation poles are formed in the filter response due to bypass coupling between the non-sequential pair of resonator stages through the bypass coupling aperture.
  • the preferred U-shaped arrangement of the resonator stages enables the formation of attenuation poles, without using an external bypass connection, by permitting inductive or capacitive bypass coupling through the bypass aperture.
  • US2005/116797 discloses a voltage-controlled tunable filter which includes a plurality of coaxial combline resonators and wherein at least one of said plurality of coaxial combline resonators includes at least one metallized through-hole.
  • the coupling between adjacent resonators is obtained via an aperture formed on a common wall between the resonators, and is controlled by the aperture size and position.
  • An input/output coupling metallization on at least one surface of said plurality of coaxial combline resonators is included as well as at least one tunable varactor associated with said plurality of coaxial combline resonators.
  • An iris connects said plurality of coaxial combline resonators.
  • the tunable dielectric capacitors can include a substrate having a low dielectric constant with planar surfaces and the substrate can be include a tunable dielectric film of low loss tunable dielectric material.
  • the input/output coupling metallization can be metallized with a predetermined length, width, and gap distance and low loss isolation material can be used to isolate the outer bias metallic contact and the metallic electrode on the tunable dielectric.
  • EP 0 208 424 discloses a filter formed by coupling plural resonators (13i, 13o) via an electromagnetic field.
  • Each resonator comprises a tubular dielectric (1) having at least one flat side surface (3), a through-hole (2) provided in the axial direction of the dielectric, an inner conductor film (4) provided on a wall forming the through-hole, and an outer conductor film (5) provided on side surfaces (7,8,9) of the dielectric (1), and resonates in TEM mode in the axial direction by cooperation of the inner conductor (4), outer conductor (5) and the dielectric (1) intervening between them.
  • Each resonator further has a coupling window (6) which is formed by removing a part of the outer conductor film (5) on the flat side surface (3).
  • the resonators (13i, 13o) are disposed so that their flat side surface (3) having the coupling windows (6) contact each other, and are coupled together via electromagnetic field through the coupling windows.
  • EP 1 544 939 discloses a hybrid filter assembly having a first ceramic triple-mode mono-block resonator, a second ceramic triple-mode mono-block resonator and at least one metallic resonator coupled to at least one of the first and second mono-block resonators.
  • Each triple-mode mono-block resonator supports three resonant modes and each metallic resonator supports an additional mode, thereby providing a hybrid filter assembly of reduced size having more than six poles.

  • FIGs 1A and 1B illustrate a conceptual structure of a resonator assembly according to an embodiment of the invention.
  • the resonator assembly may be comprised of concatenated ceramic resonators designed to provide a pass band on radio frequencies (RF).
  • RF radio frequencies
  • State-of-the-art manufacturing methods enable manufacturing of ceramic resonators that provide resonating frequencies up to microwave frequencies, e.g. super high frequencies from 0.3 to 30 Gigahertz.
  • the resonator assembly may be built from a plurality of ceramic resonator articles 100, 102 attached to each other (see Figure 1B ).
  • a first ceramic resonator article 100 may provide one or more resonance frequencies, while a second ceramic resonator article 102 may provide one or more resonance frequencies on frequencies different from that/those of the first ceramic resonator article 100.
  • Each ceramic resonator article may resonate at more than one frequencies.
  • a dual-mode ceramic resonator may provide two resonance frequencies, while a triple-mode ceramic resonator may provide three resonance frequencies. Combination of resonance frequencies of the ceramic resonator articles attached together may define the pass band of the resonator assembly.
  • the resonance properties of the ceramic resonators may be modified by reshaping the ceramic resonators.
  • the reshaping may comprise grinding ceramic material off from the ceramic resonators. This process requires very high accuracy, e.g. the tolerances may be in the order of micrometres, and the reshaping is typically carried out manually which is time-consuming.
  • Another feature of conventional methods is that the ceramic resonators are plated completely with conductive plating and a pattern is formed in the surface of the plating, e.g. by employing laser pattern forming techniques. If the resonator does not have the desired properties, the plating needs to be removed at least from one surface of the ceramic resonator in order to reshape the ceramic material. Then, the plating and the patterning needs to be repeated which is time-consuming.

  • the RF resonance characteristics of the ceramic resonator articles 100, 102 of the resonator assembly may differ from each other.

  • An effect of the present embodiment is that the tuning of the resonator assembly properties may be carried out by modifying or replacing the coupling sheet. This brings the advantage in that the replacement of the coupling sheet is fast and easy to perform.
  • the resonator assembly forms a filter apparatus.
  • the filter apparatus may be a duplex filter or a filter configured to be disposed on a single signal line, e.g. it may comprise only one input and only one output.
  • a ceramic resonator article may be an object or a body made of ceramic material.
  • the material, shape, and dimensions of the article may be designed such that the ceramic resonator article has the determined frequency characteristics, e.g. the determined resonance properties.
  • the coupling sheet may be soldered to the ceramic resonator articles 100, 102.
  • the material of the coupling sheet may be copper, silver, or another metal alloy with high conductive plating.
  • sides of the first ceramic resonator article and the second ceramic resonator article facing the coupling sheet are smooth.
  • the side(s) of each ceramic resonator article comprised in the apparatus and facing a coupling sheet is/are smooth.
  • smooth it is meant that the side does not comprise any pattern, recession, protrusion, and/or hole. The smooth surface may improve the positioning of the coupling sheet.
  • At least one of the first ceramic resonator article and the second ceramic resonator article is completely enclosed. In some embodiments, all the ceramic resonator articles of the resonator assembly are completely enclosed. In another embodiment, a subset of the ceramic resonator articles of the resonator assembly is completely enclosed. A completely enclosed ceramic resonator articles may contain no cavities, holes, or recessions.
  • the pattern may be formed into the coupling sheet by employing laser cutting, water cutting, stamping, or any other mass production method used in patterning metallic sheets.
  • the pattern may comprise determined geometrical shapes that tune the frequency characteristics of the resonator assembly.

  • Figure 1C illustrates an embodiment where a plurality of coupling sheets 104, 110 are disposed between the ceramic resonator articles 100, 102 in a layered manner.
  • the coupling sheets 104, 110 may have the same pattern 106 or different patterns 106, 112, 114.
