    摘要: A method of adjusting characteristics of a dielectric filter having integral electromagnetic shielding, the dielectric filter comprises a dielectric body having an outer surface including first and second end surfaces and side surfaces extending between the first and second end surfaces; an external conductor disposed on the outer surface of the dielectric body and providing integral electromagnetic shielding of the dielectric filter; at least one hole extending through the dielectric body between the first and second end surfaces; a respective pair of internal conductors provided in the at least one hole and conductively connected to the external conductor at respective ends of the hole, a respective non-conductive portion in the hole being spaced from both ends and thereby separating the pair of internal conductors and defining a respective capacitance between the pair of internal conductors; and signal input and output electrodes provided on the outer surface of the dielectric body and electrically isolated from the external conductor. According to the method, a portion of the dielectric material is removed, for example by grinding, to form the respective non-conductive portion in the hole. The hole may have a changing diameter along its length, due to a hollow formed in one end surface, the non-conductive portion being adjacent to the hollow; or due to a narrowed throttle portion formed at or near the end surface, the non-conductive portion being formed on the throttle portion. Alternatively, the hole may have a substantially constant cross-section, and the non-conductive portion may be substantially flush with the inner surface of the hole. The dielectric body may be regular in shape or may have a side surface with portions spaced from the resonator hole by different respective distances.

    摘要: A dielectric filter is provided which permits one to obtain desired external coupling easily without lowering Qo of resonators. The filter comprises a dielectric block having an open end surface and a shorted end surface and provided with resonator holes. Excitation holes are formed in the block outside the resonator holes, respectively. Input/output electrodes are formed on the open end-surface. The electrodes are electrically connected with conductors formed inside the excitation holes but isolated from an outer conductor. The conductors inside the excitation holes are electrically connected with the outer conductor on the shorted end surface. The excitation holes are electromagnetically coupled to the respective adjacent resonator holes, thus providing external coupling.

Near the open end of the inner conductor of the resonator hole, a non-conducting portion is formed by partially removing the inner conductor in the axial direction, at a position opposing to an adjacent through hole, or a position near the outer conductor, so as to increase odd mode or even mode characteristic impedance near the open end, whereby inductive coupling is adjustable.
