Description
SMA Plug (Male) to N Jack (Female) | Straight Adapter | Screw-lock | Stainless Steel Body
The ROSNOL AD-A1N25B/HXX-HX is a precision SMA-to-N straight adapter designed for high-frequency RF systems. It supports DC to 12 GHz with 50 Ω impedance, VSWR ≤ 1.15 (≥ 23.13 dB return loss), and insertion loss ≤ 0.05√f (GHz) dB. Electrical performance includes insulation resistance ≥ 5 GΩ, RF leakage ≥ 100 dB up to 1 GHz, and power handling up to 200 W at 2 GHz. Mechanical reliability is ensured with screw-lock coupling, ≥ 500 mating cycles, and torque ranges of 0.80–1.10 Nm (SMA) and 0.70–1.10 Nm (N).The center contacts for both SMA and N interfaces are phosphor bronze with 3 μinch gold plating over 80 μinch non-magnetic nickel-phosphorus underplating. Bodies and coupling nuts are stainless steel with passivated finish, while PTFE insulators provide excellent dielectric properties. Silicone rubber gaskets ensure environmental sealing for robust performance.
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.
