摘要： A chip device having a ground electrode and a plurality of top-surface electrodes on a plate-like dielectric substrate. Two of the top-surface electrodes are connected to the ground electrode via respective short-circuit side-surface electrodes to form quarter wavelength resonant lines. A third top-surface electrode is provided between the two top-surface electrodes and both ends thereof are opened to form a half wavelength resonant line. The two top-surface electrodes each have a parallel portion arranged near and in parallel to the third top-surface electrode and a flexion that curves from the parallel portion, extends toward the remaining of the two top-surface electrodes, and is jump-coupled to the remaining of the two top-surface electrodes. The short-circuit side-surface electrodes are jump-coupled to each other, like the flexions.

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 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 filter which corrects the mismatch of the resonance frequencies of resonators formed by internal conductors between a balanced terminal side and an unbalanced terminal side of the filter, and which is capable of easily obtaining a predetermined external coupling capacitance. Also, a dielectric duplexer, and a communication apparatus having the filter are obtained. Inside a dielectric block, a plurality of internal-conductor holes have different cross-sectional sizes, in which both ends thereof are open and internal conductors are formed on the inner surfaces. Also, the outer surface of the dielectric block is formed with an external conductor over four surfaces, but not on the opening surfaces of both ends of the internal-conductor holes. A pair of balanced terminals are coupled to the ends of one of the internal conductors, and an unbalanced terminal is coupled to one of the end portions of another internal conductor. An external-conductor-removed section may also be formed in a portion in the vicinity of the end portion of the other internal conductor. In this manner, the dielectric filter is formed.

摘要： A communication device in which the problem caused by separately providing an antenna and a filter directly connected thereto, and the problem caused by separately providing a balanced-to-unbalanced transformer, have been solved. A dielectric filter having a both-end opened &lgr;/2 resonator is constructed by providing inner-conductor forming holes in a dielectric block. An antenna is constructed by forming a radiation electrode and terminal electrodes on a dielectric block. By bonding the antenna and dielectric filter, an antenna device is achieved which has a balanced feed antenna and which performs the input-output of unbalanced signals.

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.
