SMA Jack (Female) Straight Connector 4 Hole Flange, 8.64mm (.340 inch) DC-18GHz VSWR1.30

SMA Female Connector with Stub Terminal | Stainless Steel Body | 4-Hole Flange

The ROSNOL SMA2GFA50-2540A/9X is an SMA Jack (Female) connector engineered for broadband RF performance from DC to 18 GHz. Designed with a precise 50 Ω impedance, VSWR ≤ 1.30, insertion loss ≤ 0.05 × √F (GHz), and a working voltage of 480 V rms, it provides stable high‑frequency transmission for RF modules, instrumentation interfaces, and cavity‑mounted system architectures. Additional electrical parameters include insulation resistance ≥ 5 GΩ, center‑contact resistance ≤ 3 mΩ, outer‑contact resistance ≤ 2 mΩ, and a power‑handling capability of up to 200 W at 2 GHz. The 4‑hole flange mount features 8.64 mm (0.340 inch) hole spacing to ensure accurate, repeatable installation on panels or enclosures.

Mechanical construction is optimized for durability and consistent performance, incorporating a screw‑lock coupling mechanism with ≥ 500 mating cycles. The solder‑type stub terminal supports secure conductor attachment, while the captivated centre contact provides axial captivation ≥ 27 N and radial stability ≥ 3 Ncm. High‑grade materials ensure broadband stability: the centre contact is beryllium copper with gold plating over a non‑magnetic nickel‑phosphorus underplate; the stainless‑steel body is passivated for enhanced corrosion resistance; and the PTFE insulator maintains reliable dielectric properties across the full operating band.

ROSNOL’s RF connectors offer high performance at competitive pricing, serving as dependable alternatives to major European and American brands. All ROSNOL components are produced in ISO 9001‑certified facilities and fully comply with RoHS and REACH requirements, ensuring global safety and environmental assurance. Customization services for materials, plating specifications, and mechanical design are available to support specialized RF and microwave system integration needs.
