Description
SMA Plug (Male) to N Jack (Female) | Bulkhead Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1N25A-BH/911-94 is a high-quality SMA-to-N bulkhead adapter designed for RF and microwave applications. It supports DC to 11 GHz with 50 Ω impedance, VSWR ≤ 1.20, insertion loss ≤ 0.04√f (GHz) dB, and RF leakage ≥ 100 dB up to 1 GHz. Electrical specifications include insulation resistance ≥ 5×10³ MΩ and power handling up to 200 W at 2 GHz. Mechanical integrity is ensured with screw-lock coupling, ≥ 500 mating cycles, and torque range of 0.7–1.1 Nm.The SMA and N contacts are beryllium copper with gold plating over nickel-phosphorus underplating. SMA body and coupling nut are brass with gold plating, while N body and fastening hardware use brass with copper-tin-zinc alloy finish. PTFE insulators provide superior dielectric properties, and silicone rubber gaskets ensure environmental sealing for reliable operation.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
