Description
SSMA Jack (Female) Connector | 2-Hole Flange Mount | Stub Terminal | Stainless Steel Body
The ROSNOL SSMA2GTA50-1857A/9X is a high-performance 50Ω SSMA Jack (Female) connector engineered for microwave and high-frequency applications up to 18 GHz. Featuring a 2-hole flange mount design with 8.3 mm (.328 in) hole spacing, this connector offers VSWR ≤ 1.30, insertion loss ≤ 0.03 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, and power handling up to 200 W at 2 GHz. Its compact SSMA interface provides excellent electrical performance while supporting high-density RF system designs.
The center contact is manufactured from beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplating for superior conductivity and wear resistance. The stainless steel body is passivated to enhance corrosion resistance and mechanical durability, while the PTFE insulator ensures stable dielectric properties and signal integrity.
This SSMA flange connector is widely used in aerospace electronics, defense systems, satellite communications, radar equipment, microwave instrumentation, RF modules, and test & measurement platforms. Its compact footprint, excellent high-frequency performance, and rugged stainless-steel construction make it an ideal solution for advanced RF and microwave applications.
