Title:
低インダクタンスビアアセンブリを備える多層フィルタ
Document Type and Number:
Japanese Patent JP7268161
Kind Code:
B2
Abstract:
A multilayer filter may include a dielectric layer having a top surface, a bottom surface, and a thickness in a Z-direction between the top surface and the bottom surface. The multilayer filter may include a conductive layer formed on the top surface of the dielectric layer. The multilayer filter may include a via assembly formed in the dielectric layer and connected to the conductive layer on the top surface of the dielectric layer. The via assembly may extend to the bottom surface of the dielectric layer. The via assembly may have a length in the Z-direction and a total cross-sectional area in an X-Y plane that is perpendicular to the Z-direction. The via assembly may have an area-to-squared-length ratio that is greater than about 3.25.
