Abstract (en)

[origin: EP2256752A2] The transformer (21) has a primary winding (23) with a turn formed of a conductive track made in a metallization level (M1). A secondary winding (25) includes a turn formed of a conductive track made in another metallization level (M2) isolated from the former level. Width of the track of the primary winding is larger than width of the track of the secondary winding and equal to total width of the secondary winding. The secondary winding is placed under an outer part of the primary turn such that outer perimeters of the windings coincide with each other. An independent claim is also included for a method of adjusting a transformation factor of a millimeter wave transformer.
