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 | Solder Attachment

The ROSNOL SMA2GFA50-1394A/9X is an SMA Jack (Female) connector designed for broadband RF performance from DC to 18 GHz. Engineered with a controlled 50 Ω impedance, VSWR ≤ 1.30, insertion loss ≤ 0.05 × √F (GHz), and a working voltage of 480 V rms, it supports stable high‑frequency transmission in precision RF modules, instrumentation interfaces, and cavity‑mounted assemblies. Electrical characteristics include insulation resistance ≥ 5 GΩ, center‑contact resistance ≤ 3 mΩ, outer‑contact resistance ≤ 2 mΩ, and power handling up to 200 W at 2 GHz. The 4‑hole flange mount incorporates 8.64 mm (0.340 inch) hole spacing, enabling secure and repeatable installation in panel and enclosure applications.

Mechanical construction is optimized for durability, featuring a screw‑lock coupling mechanism with ≥ 500 mating cycles. The solder‑type stub terminal provides reliable conductor attachment, while the captivated center contact delivers axial captivation ≥ 27 N and radial stability ≥ 3 Ncm. Piece parts are manufactured from high‑grade materials to ensure long‑term 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 corrosion resistance; and the PTFE insulator offers consistent dielectric performance across the full operating band.

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