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 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.
