Semi-rigid cable assemblies, important aspects to understand

The basic form of a semi-rigid cable assembly is a coaxial transmission line consisting of a metal tube, typically a copper tube forming an outer conductor, along the center line of which a wire conductor is provided, the central wire conductor being supported by a dielectric material so as to be held on the same central axis as the outer conductor.

For semi-rigid cables, the following aspects need to be understood before use:

1. Independent microwave components.
2. Wide band application range
3. Shaping and shape retention
4. phase stability
5. Low PIM (PIM）

Semi-rigid cable assemblies are typically made of non-ferrous materials, primarily copper. When the appropriate connector is selected, this type of copper tube semi-rigid coaxial cable has extremely excellent passive intermodulation performance, making it a distributed antenna system (DAS) related equipment, including the ideal choice for modern multi-frequency wireless communication systems.

All in all, semi-rigid cable assemblies are vital microwave devices that are active in countless RF applications around the world today. Although semi-rigid technology is not new, semi-rigid components are still a popular choice for engineers due to their broadband characteristics, reliable electrical performance and phase stability.
