Abstract (en)

[origin: WO2010065113A1] The current invention provides an integrated planar transformer and electronic component that includes at least one wideband planar transformer disposed in a planar substrate, where each wideband planar transformer includes a planar substrate in a fully-cured and rigid state, a ferrite material embedded in the planar substrate, where the ferrite material is enveloped in an elastic and non-conductive material, inter-wound conductors disposed around the embedded ferrite material, where top and bottom conductors are bonded by an insulating adhesive. The top and bottom conductors are connected in an inter-connected pattern by conductive vias disposed on each side of the ferrite material and span through the layers to the conductors. The planar transformer further includes at least one center tap connected to at least one inter-wound conductor. The integrated planar transformer and electronic component further includes at least one electronic component connected to at least one terminal of the wide-band planar transformer.
