Abstract
A transformer includes a primary coil assembly and a secondary coil assembly juxtaposed in a stack and which are electromagnetically inductively coupled and substantially symmetrical to one another. The primary coil assembly includes a plurality of primary coils coplanar with first insulation layers, respectively, and symmetrical to each other, and a first via unit connecting adjacent ones of the primary coils to each other. The secondary coil assembly includes a plurality of secondary coils coplanar with a plurality of second insulation layers, respectively, and symmetrical to each other, and a second via unit connecting adjacent ones of the secondary coils to each other.
Claims20
A transformer or balun comprising:
- a plurality of electrically insulative layers disposed one atop the other, the insulative layers including a plurality of first insulation layers, and a plurality of second insulation layers,
- a primary coil assembly including a plurality of primary coils and a first via unit, the primary coils being coplanar with the first insulation layers, the primary coils exhibiting substantial symmetry with respect to each other, and the first via unit connecting adjacent ones of the primary coils to each other;
- and
- a secondary coil assembly including a plurality of secondary coils and a second via unit, the secondary coils being coplanar with the second insulation layers, the secondary coils exhibiting substantial symmetry with respect to each other, and the second via unit connecting adjacent ones of the secondary coils to each other, and
- wherein the primary and secondary coil assemblies are juxtaposed in a stack, are electromagnetically inductively coupled to each other, and are substantially symmetrical to each other.
A balun comprising:
- a plurality of electrically insulative layers disposed one atop the other, the insulative layers including a plurality of first insulation layers, and a plurality of second insulation layers,
- a primary coil assembly including a plurality of primary coils and a first via unit, the primary coils be coplanar with the first insulation layers, the primary coils exhibiting substantial symmetry with respect to each other, and the first via unit connecting adjacent ones of the primary coils to each other;
- and
- a secondary coil assembly including a plurality of secondary coils and a second via unit, the secondary coils being coplanar with the second insulation layers, the secondary coils exhibiting substantial symmetry with respect to each other, and the second via unit connecting adjacent ones of the secondary coils to each other,
- wherein the primary and secondary coil assemblies are juxtaposed in a stack, are electromagnetically inductively coupled to each other, and are substantially symmetrical to each other;
- and
- a tap providing a ground for the second via unit.
