N Plug (Male) to SMA Jack (Female) | Straight Adapter | Screw-Lock | Stainless Steel Body
The ROSNOL AD-N1A25A/HXX-9X is a high-performance N Plug (Male) to SMA Jack (Female) straight RF adapter optimized for precision signal transmission from DC to 11 GHz. Designed with 50 Ω impedance, it delivers a typical VSWR of ≤ 1.20 (return loss ≥ 20.83 dB) and low insertion loss ≤ 0.03 × √F (GHz), ensuring minimal signal degradation. The N connector delivers excellent durability, high power handling, and strong environmental resistance, making it ideal for demanding mechanical conditions, while the SMA connector provides high-frequency accuracy, repeatability, and compact interconnection performance. The adapter supports up to 200 W at 2 GHz and maintains excellent electrical stability with insulation resistance ≥ 5 GΩ. Its screw-on coupling mechanism ensures reliable engagement with a minimum of 500 mating cycles.
This version features a stainless steel body with passivation treatment, offering superior corrosion resistance and mechanical strength compared to brass alternatives, making it suitable for harsh or outdoor environments. The SMA center contact utilizes beryllium copper with gold plating for enhanced elasticity and electrical conductivity, while the N side uses phosphor bronze with equivalent high-performance plating. PTFE insulators ensure stable dielectric properties across wide temperature ranges. Stainless steel construction improves durability and corrosion resistance, although it typically comes at a higher cost and slightly lower conductivity than brass.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
