Coaxial cables are cables for asymmetrical data or resp. signal transmission
The inner conductor is surrounded by a concentric dielectric; the outer conductor is applied on top in the form of a shield, serving as outer conductor and screen. A special challenge is when multi-layer dielectrics, multiple shielding and semiconductor layers are processed in high-end coaxial cables.
High-end coaxial cables are usually measurement cables
In order to obtain the smallest diameter, max. weight reduction and highest signal integrity, a very specific dielectric is applied – a microporous PTFE dielectric with an outstanding dielectric constant εr and loss angle tanδ.
