ABSTRACT:
An impedance transformer includes a first winding and a second winding. The first winding includes a first plurality of winding components, wherein each of the first plurality of winding components is on a corresponding layer of a first set of layers of a supporting substrate. The second winding includes a second plurality of winding components, wherein each of the second plurality of winding components is on a corresponding layer of a second set of layers of the supporting substrate and the first and second sets of layers are interleaved. The first winding has a first impedance within a desired frequency range and the second winding has a second impedance within the desired frequency range, where the first and second impedances are based on at least one of spacing, trace width, and trace length of the first and second plurality of winding components.
