摘要： A dielectric filter which has suitable attenuation characteristics and which readily exhibits desired characteristics. First, second and third inner-conductor holes having an inner conductor on each of the surfaces thereof are formed inside a dielectric block having an outer conductor on the outer surface thereof. First and second I/O electrodes extend from opposing side-surfaces to the undersurface of the dielectric block and are separated from the outer conductor. The side-surfaces are orthogonal to the direction in which the inner-conductor holes are arrayed in the dielectric block, and the undersurface is a mounting surface for facing a mounting board. The first I/O electrode extends from one of said side-surfaces near the first inner-conductor hole, to a position beyond a remote side of the second inner-conductor hole, that is, the side near the third inner-conductor hole.

摘要： A dielectric block includes a plurality of plated through holes each having an inner conductor formed thereon to form respective plated through holes. At least one of the plated through holes branches into two legs at the short circuit side thereof so that the two legs are close to the short circuit side of the plated through holes adjacent thereto. This allows the resonators formed of the plated through holes to be strongly inductively coupled with each other.

摘要： A dielectric filter in which many attenuation poles can be generated, including attenuation poles generated by tap coupling, so that arbitrary passing characteristics and attenuation characteristics can be obtained. In this filter, inside a dielectric block there are formed through-holes having stepped structures in which inner conductors are disposed on the inner surfaces of the holes to capacitively couple the resonators. There are also formed lateral holes having conductive films disposed on the inner surfaces of the holes. The lateral holes are connected to input/output terminals in predetermined positions of the inner conductors. Further, terminal electrodes may be disposed adjacent to predetermined positions of the inner conductors. With this arrangement, attenuation poles are generated by both distributed constant resonator coupling and tap coupling on the low frequency side and/or the high frequency side of a pass band.

摘要： The open faces of resonator holes of a dielectric filter are capable of being formed with high dimensional precision by a simple process, by which a coupling between resonators and an external coupling can easily be adjusted. In addition, a duplexer including the dielectric filter, and a communication apparatus including at least one of the dielectric filter and the duplexer are provided. The dielectric filter includes a dielectric block having protrusions on the upper surface of a substantially rectangular-parallelepiped base. Resonator holes are disposed by penetrating from the end faces of the protrusions to the lower surface of the base that opposes the end faces. External coupling holes are disposed by penetrating the opposing upper and lower surfaces of the base. An inner conductor is formed on the inner surface of each hole, and an outer conductor is formed on the substantially entire outer surface of the dielectric block except the end faces of the protrusions. Additionally, input and output electrodes separated from the outer conductor are formed at the openings of the external coupling holes on the lower surface of the dielectric block.

摘要： A dielectric filter and a dielectric duplexer have simple structures, in each of which the resonance frequency of a TE mode is controlled in such a manner that no TE-mode spurious response occurs in a band requiring attenuation. Specifically, the distance between the central position of each of inner-conductor-formed holes and a widthwise line of a dielectric block is set to be two times or more than the distance between the central position of each of the holes and a lengthwise line thereof. With this arrangement, the resonance frequency of a spurious mode such as a TE101 mode is shifted to the low-frequency side to deviate the resonance frequency of the spurious mode from a band requiring attenuation, for example, from a band near the second-order harmonic of a TEM mode, as a mode to be used. In addition, a communication apparatus is formed by using one of the filter and the duplexer described above.

摘要： A dielectric filter and a dielectric duplexer have structures for coupling between resonators, in which a range for determining the coupling strength between the resonators can be broadened and the polarity of the coupling can be changed. In addition, a communication apparatus incorporating the dielectric filter or the dielectric duplexer can be provided. Inside a dielectric member, resonance line holes having resonance lines formed on the inner surfaces thereof are disposed. Both ends of each of the resonance line holes are open-circuited. The inner diameter of each of the resonance line holes is changed at some point in the longitudinal direction of each resonance line to form a stepped part.
