ABSTRACT:
A transformer and method of making includes first half primary and secondary windings as metallic circuits that are etched on a metallic cladding of a first liquid crystal polymer (LCP) sheet. Secondary windings are positioned in spaced relation to the primary windings. A second LCP sheet is applied over the first LCP sheet. Second half primary and secondary windings are etched as metallic circuits on a metallic cladding of a second LCP sheet. Respective first and second half primary windings are interconnected to each other and the first and second half secondary windings are connected to each other by conductive vias.
