Description
N Plug (Male) to N Jack (Female) | Straight Adapter | Snap-On / Screw-Lock | Brass Body
The ROSNOL AD-NQ1N25B/944-94 is a high-performance N-to-N straight adapter for 50 Ω systems, supporting DC to 11 GHz with VSWR ≤ 1.20 and insertion loss ≤ 0.04 × √F (GHz). It features Snap-On coupling on one side and Screw-Lock on the other, delivering axial contact retention ≥ 28 N and mechanical durability of ≥ 200 and ≥ 500 mating cycles respectively. Electrical specifications include insulation resistance ≥ 5 GΩ, working voltage 500 V rms, and power handling up to 1000 W at 1 GHz and 700 W at 2 GHz.The N-side center contact is beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplate, while the Snap-On side uses beryllium copper with the same plating stack. Brass bodies and coupling nuts are finished with copper-tin-zinc alloy for enhanced protection, and PTFE dielectrics ensure low loss. The adapter offers corrosion resistance and operates from −65 °C to +165 °C.
ROSNOL’s precision-engineered RF adapters provide high quality at cost-effective pricing. All products are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. Customization for materials, plating, and mechanical design is available to support specific system needs.
