Description
SMA Plug (Male) Straight Connector | Crimped Cable Entry | Full Gold-Plated Brass Construction | RG-142
The ROSNOL SMA Plug (Male) Straight Connector, model SMA1C50-G142C/111, is designed for reliable RF signal transmission in broadband applications from DC to 6 GHz. With a controlled 50-ohm impedance, this connector delivers stable electrical performance featuring a typical VSWR of ≤ 1.20 and low insertion loss specified at ≤ 0.04 × √F (GHz) dB, supporting consistent signal integrity in RF cable assemblies.
The connector incorporates a straight, screw-on coupling mechanism and is rated for a minimum of 500 mating cycles. A crimped cable entry combined with a center contact suitable for soldered or crimped termination ensures secure mechanical retention and repeatable electrical performance. Contact resistance is strictly controlled, with center contact resistance ≤ 3 mΩ and outer contact resistance ≤ 2 mΩ, while power handling capability supports up to 200 W at 2 GHz.
The SMA1C50-G142C/111 features a fully gold-plated brass body, coupling nut, and crimp ferrules, all using non-magnetic nickel-phosphorus underplating. PTFE insulation and silicone rubber gaskets provide stable dielectric performance across a wide operating temperature range. This connector supports RG-142, RG-223, and RG-400 coaxial cables and is manufactured in ISO 9001-certified facilities with full RoHS and REACH compliance.
