A stipline coupling includes a balun-configured stripline, and a transformer-configured stripline coupled to the balun-configured stripline. The balun-configured stripline includes a pair of conductors, one of which includes a pair of coplanar conductive paths. One of the conductive paths is grounded to provide equal magnitude opposite phase signals to the transformer-configured stripline. The transformer-configured stripline impedance matches the opposite phase signals to the balanced transmission line. The transformer-configured stripline includes two conductive trace sections, one of which includes a pair of substantially abutting non-contacting conductive trace portions. The conductive trace portions of the one trace section includes fingers extending from the respective trace portion. The fingers of one of the fingered traces are interlaced with the fingers of the other fingered traces. Links extend between the fingers of the one trace section and the trace portions of the other trace section for cross-coupling the trace portions together.
