<p>HF signal transmission device comprising a HF transmission path and an LF supply current transmission path connected between common input and output terminals. The LF transmission path is provided with a blocking inductance for the HF signals which, to avoid hum modulation, comprises a series of at least two coil pairs wound on an open magnetizable core, the coils in each pair being wound in opposite sense, and the LF supply current being tapped from the junction point between the two pairs.</p> |
