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.

High-pass filter

The invention relates to an electrical socket with a housing, which has a space for inserting a connector and surrounds a contact module which comprises a number of electrical conductors and contact elements which can be contacted by associated plug contacts of the connector, two conductors respectively forming a pair of conductors. To develop the electrical socket in such a way that it can be produced at low cost and the risk of signal coupling between different pairs of conductors is reduced, it is proposed according to the invention that the contact module comprises a multi-layer circuit board which has compensation capacitors for the capacitive coupling of conductors of different pairs of conductors and means for inductive counter-coupling, in that at least the conductors of two pairs of conductors form conductor tracks in such a way that, in a first conductor track section, the distance of a first conductor track of the first pair of conductors from the first conductor track of the second pair of conductors is less than the distance from the second conductor track of the second pair of conductors, whereas, in the second conductor track section, the distance of the first conductor track of the first pair of conductors from the second conductor track of the second pair of conductors is less than from the first conductor track of the second pair of conductors.
