Representative circuit elements are analyzed, i.e. a planar bandpass filter, a buried DC-block filter and a vertical DC-feed network, which take advantage of fine line printing and high permittivity layer inclusions. In order to distinguish between manufacturing tolerances and variations occurring during the measurement, a reference sample method is introduced. All samples show good to excellent agreement with simulations as well as very little manufacturing variations up to 40 GHz. © 2007 EuMA.enTechnikIngenieurwissenschaftenConference Paper10.1109/EUMC.2007.4405278Other
