Description
QN Plug (Male) to N Jack (Female) | Straight Adapter | Quick-Lock & Screw-Lock | Brass Body
The ROSNOL AD-QN1N25A/944-94 is a precision RF adapter designed for DC to 6 GHz operation with 50 Ω impedance. It achieves VSWR ≤ 1.20 and insertion loss ≤ 0.05√F (GHz) dB, ensuring stable signal transmission and minimal loss. Insulation resistance is ≥5 GΩ, and the adapter supports ≥100 mating cycles on the QN side and ≥500 on the N side. Coupling mechanisms include quick-lock for QN and screw-lock for N, with center contact captivation ≥28 N for secure engagement.Center contacts are beryllium copper with gold plating over 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.
