Influence of Adjacent Metal Cover Planes on EMC Filter Structures

概要

論文の詳細を見る
This paper deals with the influence of metal cover planes close to SMD filter structures. The low-pass structures are used for EMC purpose and work in a frequency range of 100kHz to 4GHz. It will be shown by both measurement and simulation that a close cover plane changes the filter behavior significantly in dependency of the filter component used. For low and high impedance filter structures different influences are obtained; a parameter study was carried out in order to derive design rules.
