Published on 2/27/2026 • Updated on 2/27/2026

18GHz SMA Male to SMA Male stainless steel connector and high-frequency RF cable RG405 from SigmaRF is designed for transmitting high-frequency signals in demanding radio, microwave, and other RF applications. Manufactured by SigmaRF, these RG405 cable assemblies deliver low signal loss, excellent impedance matching, and strong anti-interference properties to guarantee precise and reliable transmission.

SigmaRF's RF high-frequency cables typically include a central conductor (solid or stranded copper or copper alloy), surrounded by an insulation layer of polyethylene, PTFE, or PVC. This is shielded by an outer conductor often copper or aluminum foil, or a copper braid for optimal grounding. The exterior insulation, made from PVC, polyethylene, or PTFE, adds durability, mechanical protection, and environmental resistance.  Call or eMail for a fast quote today!
