Abstract
For broadband applications of a balun in a magnetic field, the balun includes at least three line transformers each having two transformer sides. At least two transformer sides of the balun that belong to different line transformers of the at least three line transformers are embodied for the same voltage drop at least in terms of magnitude. The at least two transformer sides of the balun are also embodied with an identical number of turns. Two transformer sides connected in parallel are replaced by a single coil, with the result that the balun may be produced from a five-wire structure.
