The Effect of Dielectric Height and Ground Plane Width on Multilayer MCM FGCPW Lumped Elements

This paper investigates the effect of dielectric height and ground plane width on the performance of multilayer CPW transmission lines, lumped elements and circuits fabricated using photoimageable thick film technology. The effective dielectric constant and characteristic impedance are extracted to investigate the effect on transmission line dispersion. The equivalent circuit parameters for lumped elements are investigated for various dielectric thicknesses and ground plane widths. Finally, the practical effect of dielectric height is investigated for a 3GHz lumped element low pass filter.
