摘要: A mode-switching transformer with a 1-to-4 impedance ratio having first planar winding formed in conductive level from differential mode terminal outside of the winding; second via interconnection central ends and windings intended to be connected ground; at least one third two levels, interdigited or common-mode winding, internal end being for direct grounding.
