Description
SMA Plug (Male) Connector | 4 Hole Flange Mount | Stub Terminal | DC–18 GHz
The ROSNOL SMA Plug (Male) Connector, model SMA1GFA50-3050A/9XX, is engineered for panel-mounted RF applications requiring solder attachment and high-frequency performance up to 18 GHz. Designed with a 50-ohm impedance, this connector provides stable electrical characteristics with a typical VSWR of ≤ 1.30 and low insertion loss of ≤ 0.05 × √F (GHz) dB, making it suitable for precision RF signal paths.This SMA connector features a 4 hole flange mount configuration with a defined hole spacing of 8.64 mm (.340 inch), supporting secure mechanical fixation. The stub terminal, fully captivated structure, and soldered center contact ensure consistent electrical performance and mechanical reliability. A screw-on coupling mechanism supports up to 500 mating cycles, with defined torque specifications for repeatable installation quality.
The SMA1GFA50-3050A/9XX is constructed with a passivated stainless steel body and a gold-plated beryllium copper center contact using non-magnetic nickel-phosphorus underplating. PTFE insulation and silicone rubber gaskets enhance durability across wide temperature ranges. Manufactured under ISO 9001-certified processes, this connector complies with RoHS and REACH regulations.
