Apparatus and method for a radially attachable RF trap attached from a side to a shielded RF cable. In some embodiments, the RF trap creates a high impedance on the outer shield of the RF cable at a frequency of RF signals carried on at least one inner conductor of the cable. In some embodiments, an RF-trap apparatus for blocking stray signals on a shielded RF cable that has a peripheral shield conductor and a inner conductor for carrying RF signals includes: a case; an LC circuit having a resonance frequency equal to RF signals carried on the inner conductor; projections that pierce and connect the LC circuit to the shield conductor; and an attachment device that holds the case to the cable with the LC circuit electrically connected to the shield conductor of the shielded RF cable.

A multiple-layer circuit board has a signaling layer, an exterior layer, and a ground layer. A pair of differential signal lines implemented as strip lines are within the signaling layer, and propagate electromagnetic interference (EMI) along the signaling layer. An element conductively extends inwards from the exterior layer. A void of a defected ground structure within the ground layer has a size, shape, and a location in relation to the element to suppress the EMI propagated by the strip lines. A resistive material of the defected ground structure along a perimeter of the void improves suppression of the EMI propagated by the strip lines, via the resistive material absorbing the EMI.

Aspects of the subject disclosure may include, a system that guides electromagnetic waves that propagate along a transmission medium without requiring an electrical return path, and at least reduces radiation on an outer surface of a structure reducing a flow of an electrical current from an inner surface of the structure to the outer surface of the structure. Other embodiments are disclosed.

A device, in particular a pre-assembled transmission cable, is used to transmit differential data signals in a high-speed data connection. The device contains a circuit board with a conductor pair with two signal conductors for transmitting the differential data signal. An output line which is insulated from the conductor pair is paired with the conductor pair, the output line running parallel to the signal conductors in a non-interrupted manner and additionally being connected to a measuring conductor via at least one damping element. By virtue of the configuration, an undesired common-mode signal component is at least partly coupled into the output line, where the signal component is absorbed during operation.

Described herein is a system. The system comprises an output cabling comprising an output wire and a return wire. The system also comprises a surge generator configured to provide a voltage pulse at a first rise time down the output cabling to a device under test. The output wire causes a ring at an initiation of the voltage pulse being provided by the surge generator to the device under test. The return wire is a return leg of the output cabling that is in a parallel path to the output wire and is configured to reduce or eliminate the ring.
