LTCC filter modeling using EM and equivalent circuit techniques

摘要

A family of LTCC filters were modeled using a substrate-scalable equivalent circuit modeling approach. Modeling using finite-element electromagnetic analysis and physical geometries was also explored. Presented within this paper are model results for example high pass and low pass filters along with a model application example demonstrating how the models can be used for improved layout to compensate for filter parasitic effects, which vary with substrate choice.
