Abstract

RF integrated thin-film EM field shielding and inline noise suppression have been demonstrated by using Co85Nb12Zr3 amorphous film and electroplated Ni-Zn(-Co) ferrite films. The FMR loss generation at GHz frequency range is essential to realize this idea. The frequency range of loss generation can be adjusted to specific applications by materials selection and by the magnetic micro wiring technique. Insertion toss was only 0.7dB at 1GHz and reached 14 dB for a 17.2mm long coplanar transmission line with a 0.5-μm-thick Co85Nb12Zr3 film provided the in-between gap was 7.5 μm.
