N Plug (Male) to SMA Jack (Female) | Straight Adapter | Screw-Lock | Brass Body
The ROSNOL AD-N1A25A/H44-H4 is a precision-engineered N Plug (Male) to SMA Jack (Female) straight RF adapter designed for reliable 50 Ω signal transmission from DC to 11 GHz. It features a low VSWR of ≤ 1.20 (return loss ≥ 20.83 dB) and insertion loss ≤ 0.03 × √F (GHz), supporting stable high-frequency performance. The N connector provides robust mechanical strength, high power handling capability, and excellent performance in lower-frequency and outdoor environments, while the SMA connector offers compact size, high precision, and superior performance at higher frequencies. The adapter supports up to 200 W at 2 GHz and ensures consistent electrical reliability with insulation resistance ≥ 5 GΩ and low contact resistance. A screw-on coupling mechanism ensures secure mating with a minimum of 500 mating cycles.
Constructed with a brass body and copper-tin-zinc alloy plating, this RF adapter provides an effective balance between conductivity and cost-efficiency. The center contacts are made of phosphor bronze with gold plating over non-magnetic nickel-phosphorus underplating, ensuring reliable signal transmission and corrosion resistance. PTFE insulators maintain stable dielectric performance. Brass construction offers excellent electrical conductivity and machinability, though it may exhibit lower corrosion resistance compared to stainless steel in harsh environments.
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.
