An alternative approach to construct a planar integrated reactive power module is presented in this paper. Enclosed in a planar core, a few copper strips plated on both sides of a high-permittivity ceramic substrate generate a series of so-called L-C cells. Various equivalent circuits may be realized with this chip-like module using different printed circuit board PCB interconnections between the L-C cells. The experimental results show its potential as an integrated high-frequency power resonator. Good correspondence between experimental measurement and first-order models is demonstrated.
