SMA Plug (Male) to N Jack (Female) Bulkhead Adapter, DC-11GHz VSWR 1.20

SMA Plug (Male) to N Jack (Female) | Bulkhead Adapter | Screw-lock | Stainless Steel Body

The ROSNOL AD-A1N25A-BH/9XX-9X is a precision SMA-to-N bulkhead adapter designed for high-performance RF and microwave systems. It supports DC to 11 GHz with 50 Ω impedance, VSWR ≤ 1.20 (≥ 20.8 dB return loss), and insertion loss ≤ 0.04√f (GHz) dB. Electrical integrity includes insulation resistance ≥ 5×10³ MΩ, 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 range of 0.7–1.1 Nm for both interfaces.

The SMA and N contacts are beryllium copper with 3 μinch gold plating over 80 μinch non-magnetic nickel-phosphorus underplating. Bodies, coupling nuts, and fastening hardware are stainless steel with passivated finish, while PTFE insulators provide excellent dielectric properties. Silicone rubber gaskets ensure environmental sealing for robust 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.
