Description
SMA Jack (Female) | PCB Through Hole | Screw-lock | Stainless Steel Body
The ROSNOL SMA2I50-1350A/9Q connector is a precision-engineered SMA Jack (Female) designed for PCB through-hole mounting in high-frequency systems. It operates from DC to 18 GHz with a 50 Ω impedance, delivering VSWR ≤ 1.25 (≥ 19.1 dB return loss) and insertion loss ≤ 0.04 × √F (GHz) dB. Electrical performance includes insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ, and outer contact resistance ≤ 2 mΩ. Rated for 1000 V rms test voltage and 480 V rms working voltage, this connector supports power handling up to 200 W at 2 GHz and 100 W at 10 GHz, with RF leakage ≥ 100 dB up to 1 GHz.Constructed from premium materials, the center contact is beryllium copper with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. The body is stainless steel with gold plating, and the insulator is PTFE for excellent dielectric stability. Mechanical features include screw-lock coupling, ≥ 500 mating cycles, axial captivation ≥ 27 N, and torque ratings of 0.8–1.1 Nm recommended (1.7 Nm max).
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global standards. Customization services for plating, materials, and mechanical design are available upon request.
