    摘要: A single-stage dielectric band elimination filter has a dielectric block with its outer surfaces mostly covered by an outer conductor and two mutually coupled resonant lines formed therein. Each resonant line has an open end insulated from the outer conductor and a shorted end connected thereto, the open and shorted ends of the two resonant lines being oppositely oriented. A multi-stage dielectric filter has a plurality of such single-stage band elimination filters formed inside a dielectric block, each mutually adjacent pair of the single-stage band elimination filters being interdigitally coupled or combline-coupled to each other with phase shift of II/2 therebetween. The open end of a resonant line may be formed at one of the end surfaces of the dielectric block, being connected to an electrode insulated from the outer conductor, or at an annular conductor-free area formed on the inner surface of the corresponding throughhole. The resonant lines for forming the plurality of single-stage band elimination filters may be arranged horizontally or vertically with respect to each other. Screening electrodes may be inserted between mutually adjacent resonant lines.

    摘要: A compact dielectric resonator apparatus is comprised of a dielectric block having a plurality of mutually parallel throughholes formed therethrough with inner surfaces covered with a conductive film so as to provide coaxial resonators. The degree of coupling between a mutually adjacent pair of such dielectric resonators can be adjusted by forming grooves, a bottomed hole or a slit or burying a conductive plate therebetween in the dielectric block, and varying physical characteristics of such grooves, bottomed hole, slit and/or conductive plate, without changing the separations between the throughholes or the external dimensions of the dielectric block.

    摘要: To reduce the number of components and enable the mounting work of a filter unit onto a printed substrate without using a metal case, a filter unit of three-state structure with resonators is constructed in which an electrode is formed on an inner peripheral surface of each through-hole and an outer peripheral surface of a dielectric member except for one end face, and connector terminals each composed of a pin and an insert member are inserted into opening portion of the end face of the through-holes to form a dielectric bandpass filter. An enlarged insert portion is formed in the opening portion of each through-hole so as to form a stepped portion between the insert portion and a non-insert portion. The insert member has the same configuration as that of the insert portion and is inserted and fitted in the insert portion without projecting from the end face. At the same time, the movement of the insert member toward the non-insert portion is restricted by the stepped portion. The connector terminals are mounted in a stationary manner in a predetermined position within the through-holes.

    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.
