摘要： A multi-mode resonator device can be reduced in size even while increasing the number of resonators while including either a semi-coaxial resonator or a coaxial resonator. Coupling between a TEM mode as a resonance mode of the semi-coaxial resonator and a TM mode as another resonance mode can be facilitated, which enables coupling between the resonators at a predetermined coupling strength. Inside a cavity with a cover, a conductive rod and a dielectric core are disposed so as to substantially equalize a quasi-TEM-mode resonant frequency generated by the cavity and the conductive rod and a quasi-TM-mode resonant frequency generated by the cavity and the dielectric core. A coupling adjusting block is arranged at a place where the magnetic field of one of two coupling modes generated by the quasi-TEM and quasi-TM modes is strong and that of the other mode is weak. The invention also provides a filter, duplexer, and a communication apparatus using the resonator device.

摘要： A dielectric resonator device has a dielectric member. Electrodes are respectively formed on the upper and lower surfaces of the dielectric member. The dielectric resonator device resonates at a mode having electric field components in a direction perpendicular to the upper and lower surface of the dielectric member. The electrodes formed on the dielectric member are each formed of a thin film multi layered electrode produced by alternately laminating thin film electrode layers and thin film dielectric layers. Each thin film dielectric layer which is sandwiched between the thin film multi layered electrode layers serves as a dielectric resonator. Accordingly, the thin film multi layered electrode acts as a laminated structure of a plurality of dielectric resonators. Thus, a current distributes over the plurality of thin film electrode layers, thereby alleviating the current concentration on the surface of the dielectric member. As a consequence, conduction losses of the overall resonator unit are reduced.

摘要： A multi-layer thin-film electrode comprises thin conductor films and thin dielectric films each being alternately laminated on a dielectric substrate, in which an electro-magnetic field generated in the dielectric substrate and that generated in each of the thin dielectric films have substantially the same phase at a predetermined frequency. According to the multi-layer thin-film electrode of the present invention, adhesive conductor films that more readily form metallic oxide as compared with the thin conductor films are provided between the dielectric substrate and the thin conductor films adjacent thereto and between each of the thin conductor films and the thin dielectric film adjacent thereto, respectively, and an increase in the surface reactance of the thin conductor films caused by the adhesive conductor film formation is canceled by correcting the thickness of each of the thin dielectric films based on the dielectric constant of the thin dielectric film and the dielectric substrate and the thickness of at least one of the adhesive conductor films.

摘要： A dielectric resonator designed so that there is substantially no loss in a conductor on the surface of a casing forming a shielded cavity, and so that the unloaded Q and the resonant frequency can be changed independently of each other. A cylindrical dielectric block having a pair of electrodes formed respectively on its two opposite surfaces is disposed in a metallic shielded-cavity casing so that one of the electrodes is in contact with an inner bottom surface of the shielded-cavity casing. This electrode is electrically connected to the shielded-cavity casing by soldering or the like. Input/output connectors are coupled to the other electrode on the cylindrical dielectric block.

摘要： A multimode dielectric resonator apparatus is configured such that a TM mode and a TE mode are transformed into multiplex modes, coupling between individual resonant modes can be easily made, and a large number of sequentially coupled stages can be obtained with a single dielectric core. In the multimode dielectric resonator apparatus, a dielectric core is configured of a plate-like TM-mode dielectric core portion and a TE-mode dielectric core portion protruding therefrom in the vertical direction, for example in a spherical shape. Five modes, namely a TMx mode, a TMy mode, a TEx mode, a TEy mode, and a TEz mode are used as multiplex modes. In addition, a filter and a duplexer use the multimode dielectric resonator apparatus, and a communication apparatus uses one or both of the filter and the duplexer.
