N Snap-On Plug (Male) to SMA Jack (Female) | Straight Adapter | Snap-Lock & Screw-Lock | Brass Body
The ROSNOL AD-NQ1A25A/H44-94 is a straight RF adapter engineered for reliable interconnection between N snap-on plug male and SMA jack female terminations. It supports DC to 11 GHz frequency range with 50-ohm impedance, VSWR ≤ 1.20, and insertion loss ≤ 0.04√F (GHz) dB. Electrical specifications include insulation resistance ≥ 5×10³ MΩ, test voltage 1000 V rms, working voltage 480 V rms, and power handling up to 200 W at 2 GHz. RF leakage is ≥ 100 dB up to 1 GHz. The adapter employs snap-lock coupling on the N side and screw-lock on the SMA side, rated for at least 200 mating cycles on the N side and 500 cycles on the SMA side, and features axial captivation ≥ 28 N.
Material and plating details are optimized for corrosion resistance and RF stability. Both center contacts are phosphor bronze with gold plating over nickel-phosphorus underlayer, and bodies are brass with copper-tin-zinc alloy finish. PTFE insulators provide excellent dielectric properties, and silicone rubber gaskets ensure environmental sealing. The adapter operates in temperatures from -65°C to +165°C.
ROSNOL’s precision-engineered RF adapters offer consistent quality and competitive pricing, serving as a practical alternative to major European and American brands. All ROSNOL RF components are manufactured under ISO 9001-certified processes and comply with RoHS and REACH standards. Customization options for materials, plating, and mechanical design are available to meet specific application requirements.
