Title:
STACKED DIELECTRIC FILTER
Document Type and Number:
Japanese Patent JP3312726
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To adjust the position of an attenuation peak and to easily obtain a target characteristic without changing the induction connection between resonance elements in the stacked dielectric filter of a same passband characteristic.
SOLUTION: A stacked body 12 where an input terminal, an output terminal and a ground electrode are formed on an outer peripheral face, two resonance elements 14a and 14b installed in the stacked body 12, a connection adjusting electrode 70 which is installed between the resonance element 14a of an input side and the resonance element 14b of an output side and which is capacity- connected to the resonance elements 14a and 14b, an input side adjusting electrode 66 for forming a capacitance between the input terminal and the connection adjusting electrode 70 and an output side adjusting electrode 68 for forming a capacitance between the output terminal and the connection adjusting electrode 70 are installed.
