N Plug (Male) to UHF Jack (Female) Adapter, DC-300MGz VSWR 1.3

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

The ROSNOL AD-N1U25A/H44-H4 is a straight RF adapter designed for secure connectivity between N plug male and UHF jack female interfaces. It operates from DC to 300 MHz with N side impedance of 50 ohms and UHF side non-constant impedance. VSWR is ≤ 1.3, ensuring return loss ≥ 17.7 dB. Electrical performance includes 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 features screw-lock coupling on both sides, axial captivation ≥ 28 N (N side) and ≥ 30 N (UHF side), and supports at least 500 mating cycles.

Material construction ensures durability and signal integrity. Both center contacts are phosphor bronze with gold plating 3 microinch over a non-magnetic nickel-phosphorus underplating 80 microinch; bodies are brass with copper-tin-zinc alloy finish, and insulators are PTFE. Silicone rubber gaskets and brass coupling nuts provide environmental sealing. The adapter operates reliably from -55°C to +165°C.

ROSNOL’s precision-engineered RF adapters deliver high quality and dependable performance at competitive pricing, making them an ideal alternative to leading European and American brands. All ROSNOL components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to meet specialized interconnect requirements.
