Title:
阻止帯域減衰特性を改善した積層型フィルター
Document Type and Number:
Japanese Patent JP3972046
Kind Code:
B2
Abstract:
Disclosed herein is a laminated filter with improved stop band attenuation, which is adopted in devices using a radio frequency, such as communication systems and/or broadcasting systems. The laminated filter forms cross capacitive coupling as feeding lines of input lead and/or output lead are coupled to a resonator pattern, and enhances an attenuation characteristic of stop band. Also, the laminated filter is minimized if feeding lines of the input lead and output lead are aligned in different layers, and the positions of the attenuation poles are easily controlled by adjusting the feeding line length.
