ABSTRACT:
The invention relates to a high-pass filter comprising a signal line with several capacitors connected in series as well as a ground line, wherein several inductors are connected between the signal line and the ground line. In order to configure the high-pass filter as a coaxial construction it is suggested in accordance with the invention that the signal line form an inner conductor and the ground line an outer conductor of a coaxial conductor, between which an insulation layer is arranged, and that the inductors be designed as discrete components which are arranged at a distance to one another and between which at least one impedor is connected.
