LAMINATED FILTER AND LAMINATED MODULE

摘要

PROBLEM TO BE SOLVED: To provide a laminated filter, with which impedance matching is easily taken and an external electrode at the side face of the dielectric body is easily formed and the laminated module with a good characteristics and to which circuit components are easily mounted to a portable telephone set. ;SOLUTION: A dielectric constant of a dielectric layer between a resonator electrode 103 and capacitor electrodes 105, 106 is selected higher than a dielectric constant of other dielectric layers. Then a land electrode is formed to an upper face of an uppermost dielectric layer, circuit components are mounted to form a low-pass filter and a high-frequency switch circuit, and they are connected by external electrodes 110-113 provided to the side face of the dielectric body.;COPYRIGHT: (C)1998,JPO
