Abstract

The present embodiments relate to a balanced-to-unbalanced transformer for converting a symmetrical high-frequency signal into an asymmetrical high-frequency signal. The balanced-to-unbalanced transformer includes two coil windings made of wire. The two coil windings are electrically insulated from each other and are wound on a winding form. Each of the two coil windings has an input at one end of the winding form for the symmetrical high-frequency signal and an output at another end of the winding form for the asymmetrical high-frequency signal. The two coil windings lie on top of one another in a radial direction of the winding form.
