SMA Plug (Male) to N Jack (Female) | Straight Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1N25A/H11-H4 is a precision 50 Ω RF adapter engineered for dependable connectivity between SMA Plug (Male) and N Jack (Female) interfaces. Operating from DC to 12 GHz with VSWR ≤ 1.15 and low insertion loss, it supports stable signal transmission across a broad frequency range. The screw-on coupling system and minimum 500 mating cycles ensure reliable mechanical performance.
The center contacts are manufactured from phosphor bronze with gold plating over a non-magnetic nickel-phosphorus underplating. Phosphor bronze provides excellent durability and electrical conductivity. The adapter body is made from brass, with gold-plated SMA components and a copper-tin-zinc alloy finish on the N-side body. Brass delivers excellent mechanical strength and machining characteristics, while the plating enhances corrosion resistance and surface durability. PTFE insulators and silicone rubber sealing components support long-term reliability.
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.
