摘要： A laminated dielectric filter has a plurality of resonant elements disposed on a dielectric layer which constitute quarter-wave stripline resonators, respectively. The resonant elements have ends connected to a ground electrode. The dielectric layer also supports a plurality of electrodes having ends connected to the ground electrode and opposite ends spaced from and confronting respective open ends of the resonant elements. The laminated dielectric filter has another dielectric layer which supports thereon an electrode positioned in overlapping relationship to the resonant elements. Still another dielectric layer supports an input electrode positioned in overlapping relationship to the resonant elements and the electrode on the other dielectric layer and an output electrode positioned in overlapping relationship to the resonant elements and the electrode on the other dielectric layer. The laminated dielectric filter provides an attenuation pole to improve attenuation characteristics, suffers less variation of frequency at the pole, and can easily be reduced in size.

摘要： A circuit board that can decrease thermal stress acting between a semiconductor element and a board in association with temperature alteration and has high mechanical strength (rigidity) as a whole board (including a multilayer wiring layer) is provided. Ceramic base material having a coefficient of thermal expansion close to that of a semiconductor element and inner layer wiring are integrally sintered, and the circuit board is configured so that fine-lined conductor structure corresponding to a multilayer wiring layer in the inner layer wiring has predetermined width, intralayer interval and interlayer interval. Thereby, thermal stress acting between a semiconductor element and the board when the board is exposed to temperature alteration in a condition where it is joined with the semiconductor element is suppressed, rigidity of the board is maintained, and its reliability against temperature cycle is increased.
