摘要： A balanced-unbalanced transformation device includes a plate-like dielectric substrate having a ground electrode and a plurality of major surface electrodes formed thereon. Two of the major surface electrodes are connected to the ground electrode via short-circuit side surface electrodes so as to form ¼ wavelength resonator transmission lines. A third major surface electrode is disposed between the two major surface electrodes and has either end open so as to form a ½ wavelength resonator transmission line. A balancing characteristic adjustment side surface electrode is provided on a side surface of the dielectric substrate. By adjusting a capacitance formed between the balancing characteristic adjustment side surface electrode and the third major surface electrode, a phase balance between two balanced signals is set to a desired value.

摘要： A dielectric filter with an ultra hetero-axial structure is provided with open end-face electrodes. By increasing the capacitance between each open end-face electrode and an external conductor greater than that generated between the open end-face electrodes adjacent to each other, the inductive coupling between two resonators due to neighboring resonator holes is increased.

摘要： A dielectric filter includes a dielectric block having inner-conductor-formed holes extending from a first face of the dielectric block to a second face opposed to the first face. Inner conductors are formed inside the inner-conductor-formed holes such that both ends of the inner-conductor-formed holes are open-circuited. On the exterior surface of the dielectric block, balanced input/output terminals are capacitively coupled to the open ends of the inner-conductor-formed holes. A metal cover is provided so as to cover one of the first or second face of the dielectric block. The metal cover functions as a short-circuit conductor in a spurious mode such as a TE mode other than a TEM mode, and hence the influence of the spurious mode is avoided.

摘要： A dielectric filter or a dielectric duplexer is provided which comprises a dielectric block in a substantially rectangular parallelepiped shape, having a pair of opposite parallel end-faces and plural sides extending between the paired opposite end-faces, one of the plural sides being a mounting face; plural resonator holes elongating through the inside of the dielectric block across the paired opposite end-faces; inner conductors provided on the inner walls of the plural resonator holes, respectively; an outer conductor provided on the outside of the dielectric block; input-output electrodes provided only on one of the paired opposite end-faces, separated from the outer conductor, and capacitance-coupled to the predetermined inner conductors, respectively; and conductive terminals for external connection, connected to the input-output electrodes, having at least portions thereof lying substantially in the same plane as the mounting face. In the dielectric filter or the dielectric duplexer, since input-output electrode are provided on the end-face of the dielectric block, not provided on the sides of the dielectric block, the deterioration of Q0, caused by the input-output electrodes, can be reduced. Accordingly, the insertion loss and the attenuation characteristics are improved.

摘要： A dielectric resonator apparatus contains coaxial resonators in a dielectric block made of a dielectric material, having a first end surface, a second end surface and a plurality of side surfaces therebetween. The block is formed with resonator-forming throughholes penetrating therethrough and having openings on the first and second end surfaces. Inner conductors are formed inside these resonator-forming throughholes, and an outer conductor is formed at least on the side surfaces and the first end surface. A molded resin member made of a dielectric resin material, having pin-accepting holes therethrough, is attached to the resonator-forming throughholes. Input/output terminals are formed on the molded resin member so as to be insulated from the inner and outer conductors. Metallic pins are inserted into the pin-accepting holes to thereby contact the input-output terminals and to provide external-connection capacitance with the inner conductors. A conductive film is formed at least on the second end surface or the molded resin member for preventing electromagnetic waves from leaking outside. Functional characteristics of such an apparatus can be adjusted by controlling the external-connection capacitance by varying the distance by which the metallic pins are inserted into the pin-accepting holes.
