Description
N Plug (Male) to SMA Jack (Female) | Straight Adapter | Screw-Lock | Brass Body
The ROSNOL AD-N1A25A/133-H3 is a high-performance straight RF adapter connecting N male to SMA female interfaces for reliable signal integrity. Operating from DC to 11 GHz with 50 Ω impedance, it offers VSWR ≤1.20, insertion loss ≤0.03√F (GHz) dB, insulation resistance ≥5 GΩ, test voltage 1000 V rms, and working voltage 480 V rms. Power handling reaches 200 W at 2 GHz under optimal conditions. Screw-lock coupling ensures secure engagement with axial captivation ≥28 N and durability of ≥500 mating cycles. Recommended torque ranges from 0.7 to 1.1 Nm for both sides.Center contacts are phosphor bronze with gold plating over nickel-phosphorus underplating for superior conductivity and corrosion resistance. Bodies are brass with nickel plating; insulators are PTFE; gasket is silicone rubber; coupling nut is nickel-plated brass. The adapter withstands −55°C to +155°C and complies with RoHS.
ROSNOL’s precision-engineered RF components deliver consistent quality and cost efficiency as alternatives to leading global brands. 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.
