Baluns, Chokes

A sheath wave is a type of electromagnetic wave that spreads in a conductor along the outer sheath of a coaxial line. However, they can also be generated by inducing the actual transmitted signal on the outside of the coaxial sheath. At WiMo, we not only sell a wide range of sheath wave barriers, but we also manufacture them ourselves. Contact us for your individual requirements.

FAQ

What are Sheath Waves?
A sheath wave is a type of electromagnetic wave that propagates through conductors. For example, the sheath wave propagates in a conductor along the outer sheath of a coaxial line.
How to reduce sheath waves?
A sheath wave barrier (also called a sheath wave absorber or sheath current filter) attached to a coaxial line in or near the equipment can attenuate or prevent high-frequency sheath waves. In the simplest case, it is a ferrite core that contains inner and outer conductors in coaxial cables and acts as a current-compensated choke or common-mode choke. A ferrite core also functions as a transformer so that a useful signal can be maintained as a push-pull signal. The cable can also be passed through the core several times to increase inductance against unwanted common mode signal components.
How do cladding wave filters work?
To reduce this interference, the entire cross-section of the cable is passed through a ferrite core (multiple times if necessary). Because of its inductance, this configuration acts like a choke with one or possibly more turns for common mode interference.
What are the different types of cladding wave filters?
There are split, snap-in ring and ribbon cable ferrites that can be applied to electrical cables to subsequently place ferrite cores around the cables for interference suppression. Snap-in ferrites are another name for cladding wave filters..
