Description
SMA Plug (Male) to N Jack (Female) | Bulkhead Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1N25A-BH/911-93 is engineered for SMA-to-N bulkhead connections in RF systems requiring durability and precision. Rated for DC to 11 GHz, it offers 50 Ω impedance, VSWR ≤ 1.20, insertion loss ≤ 0.04√f (GHz) dB, and RF leakage ≥ 100 dB up to 1 GHz. Electrical performance includes insulation resistance ≥ 5×10³ MΩ and power handling up to 200 W at 2 GHz. Mechanical features include 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 for optimal conductivity. SMA body and coupling nut are brass with gold plating, while N body and fastening hardware are brass with nickel finish. PTFE insulators ensure excellent dielectric performance, complemented by silicone rubber gaskets for environmental sealing.
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.
