Description
SMB Plug (Male) to N Jack (Female) | Straight Adapter | Snap-On & Screw-Lock | Brass Body
The ROSNOL AD-S1N25A/911-94 is a precision RF adapter designed for DC to 4 GHz operation with 50 Ω impedance. It achieves VSWR ≤ 1.35 and insertion loss ≤ 0.05√F (GHz) dB, ensuring stable signal transmission and minimal loss. Insulation resistance is ≥1 GΩ, and the adapter supports ≥500 mating cycles on both sides. Coupling mechanisms include snap-on for SMB and screw-lock for N, with center contact captivation ≥10 N for secure engagement.
Center contacts are beryllium copper with 3 microinch gold plating over an 80 microinch nickel-phosphorus underplating. Bodies and coupling nuts are brass with corrosion-resistant finish, and insulators are PTFE. Recommended torque for the N side is 0.7–1.1 Nm. The operating temperature range spans −65°C to +165°C, ensuring durability under harsh conditions.
ROSNOL’s precision-engineered RF adapters deliver reliable performance and cost-effective alternatives to leading global brands. All components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. Customization for materials, plating, and mechanical design is available to meet specialized requirements.
