Description
SMA Plug (Male) to N Jack (Female) | Straight Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1N25A/H44-H4 is a high-performance RF adapter engineered for reliable interconnection between SMA Plug (Male) and N Jack (Female) interfaces. With a frequency range from DC to 12 GHz, VSWR ≤ 1.15, and low insertion loss, the adapter supports efficient signal transmission in 50 Ω RF systems. The threaded coupling design ensures secure mating and long-term durability.
The center contacts are manufactured from phosphor bronze with gold plating over a non-magnetic nickel-phosphorus underplating. This material combination delivers excellent conductivity and wear resistance. The body and coupling nut are manufactured from brass with a copper-tin-zinc alloy finish. Brass provides robust mechanical properties and ease of precision machining, while the copper-tin-zinc alloy coating enhances corrosion protection and environmental durability. PTFE insulators contribute to stable electrical performance.
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.
