N Plug (Male) to UHF Plug (Male) Adapter, DC-300MHz VSWR 1.3

N Plug (Male) to UHF Plug (Male) | Straight Adapter | Screw-Lock | Brass Body

The ROSNOL AD-N1U15A/133-133 is a straight RF adapter engineered for reliable interconnection between N plug male and UHF plug male terminations. It supports DC to 300 MHz frequency range with N side impedance of 50 ohms and UHF side non-constant impedance. VSWR is ≤ 1.3, ensuring return loss ≥ 17.7 dB. Electrical specifications include insulation resistance ≥ 5 GΩ, center contact resistance ≤ 1 mΩ on the N side and ≤ 5 mΩ on the UHF side, and outer contact resistance ≤ 0.25 mΩ on the N side and ≤ 5 mΩ on the UHF side. The adapter employs screw-lock coupling on both sides, rated for at least 500 mating cycles, and features axial captivation ≥ 28 N (N side) and ≥ 30 N (UHF side).

Material and plating details are optimized for corrosion resistance and RF stability. Both center contacts are brass 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 -55°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.
