A Guide to Semi-Flexible RF Cables: Types, Structure, and Applications
What are Semi-Flexible RF Cables?
Semi-flexible cables are engineered for applications operating in frequency bands from 18 GHz to 40 GHz. Their shape-memory characteristic allows them to be bent and formed while maintaining high shielding effectiveness and low signal loss. These cables are available in three diameters, with or without an outer jacket, and can be terminated with a variety of high-frequency connectors, such as SMA, N, 2.92 mm (K), and SMP.
As the applicable connectors vary by cable model, please consult the detailed product page for complete specifications.
