摘要： In an LC-type dielectric filter, an inductor is formed on the uppermost or outermost insulation or dielectric layer and electrically connected at the opposite ends thereof to an upper electrode and a lower electrode which cooperate with a thin film dielectric layer to constitute a capacitor, by means of conductive vias. A method of adjusting a frequency of an LC-type filter is also provided. By the method, an optimum inductance for an inductor is calculated based on a measured capacitance and a desired frequency of the filter, and a pattern of the inductor which is capable of attaining the optimum inductance is selected from a group of predetermined patterns which differ in inductance. The inductor is formed on the outermost dielectric layer in such a manner as to have the selected pattern.

摘要： A multilayer microelectronic circuit to be directly mounted on a substrate and to be used, for example, as a resonator. The multilayer microelectronic circuit comprises a plurality of dielectric layers and patterned electrodes which are laminated one upon another to form a laminated structure, the dielectric layers and the patterned electrodes forming an electrical circuit. The laminated structure has side surfaces extending along a direction in which the dielectric layers and the patterned electrodes are laminated. An input line is formed at one of the side surfaces and connected with an input section of the electrical circuit. An output line is formed at one of the side surfaces and connected with an output section of the electrical circuit. A grounding line is formed at one of the side surfaces and connected with a grounding section of the electrical circuit. Additionally, a signal line formed at one of the side surfaces, for connecting sections of the electrical circuit. The signal line has an end positioned adjacent a mounting surface at which the multilayer microelectronic circuit is directly mounted on the substrate, in which the end of the signal line is separate from the mounting surface so as to be insulated from electrical contact with the substrate.
