Abstract

We report fabrication of miniaturized low temperature co-fired ceramic helical (3-D) inductors with more than seven layers of helices and the conductor linewidth of 100 μm. We achieve the Q_maxL_effA product ranging from 200 to 370. Such high values are possible thanks to the drastic reduction of the active area and still acceptably large Q_max and self-resonant frequency. High frequency characterization of the inductors is performed up to 12 GHz, and a new equivalent circuit model considering vertical electromagnetic coupling between conductors is shown to reproduce all the measured characteristics.
