Description
UHF Plug (Male) to N Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-U1N25A/H33-H3 offers reliable RF performance from DC to 300 MHz with 50 Ω impedance. It achieves VSWR ≤1.30 and provides stable signal transmission for low-frequency applications. Electrical specifications include insulation resistance ≥5 GΩ, center contact resistance ≤5 mΩ (UHF) and ≤1 mΩ (N), and outer contact resistance ≤5 mΩ and ≤0.25 mΩ respectively. Coupling mechanisms include screw-lock on both ends, with ≥500 mating cycles and center contact captivation ≥30 N (UHF) and ≥28 N (N).The adapter features phosphor bronze contacts with gold plating over nickel-phosphorus underplating for optimal conductivity. Bodies and coupling nuts are brass with nickel finish, and insulators are PTFE for excellent dielectric properties. A silicone rubber gasket ensures environmental sealing. Operating temperature ranges from -55°C to +149°C for dependable performance.
ROSNOL’s precision-engineered RF adapters deliver consistent performance across high-frequency applications. Manufactured in ISO 9001-certified facilities and fully compliant with RoHS and REACH, they provide a cost-effective alternative to leading European and American brands. Customization for materials, plating, and mechanical design is available to meet specialized requirements.
