Patent ID: 8203418

Claim:
An integrated planar transformer and electronic component, comprising: a. at least one wideband planar transformer disposed in a planar substrate, wherein each said wideband planar transformer comprises: i. said planar substrate, wherein said planar substrate is in a fully-cured and rigid state; ii. a ferrite material, wherein said ferrite material is embedded in said fully-cured and rigid planar substrate, wherein said embedding comprises said ferrite material encased in an elastic and non-conductive material, wherein said elastic and non-conductive material comprises a low-stressing epoxy, wherein said low-stressing epoxy has a modulus of expansion that is lower than a modulus of expansion of said rigid planar substrate, wherein said low-stressing epoxy holds said ferrite material in place over a temperature range found in a manufacturing process or a temperature range found in operative use, wherein said ferrite is not stressed by said rigid planar substrate; iii. inter-wound conductors disposed around said embedded ferrite material, wherein said inter-wound conductors comprise top conductors bonded by a first bonding layer to a top surface of said fully-cured and rigid substrate and bottom conductors bonded by a second bonding layer to a bottom surface of said fully-cured and rigid substrate, wherein said bonding layers comprise an insulating adhesive, wherein said top and bottom conductors are connected in an inter-connected pattern by conductive vias disposed on each side of said ferrite material, wherein said conductive vias span through said bonding layers and through said low-stressing epoxy and through said fully-cured and rigid planar substrate forming said inter-wound conductors; iv. at least one center tap connected to at least one said inter-wound conductor; b. at least one electronic component; and c. at least one terminal connected to said wideband planar transformer, wherein said electronic component is connected to said at least one terminal.
