SMA Plug (Male) to N Jack (Female) RF Adapter | Screw-On | Brass Body
The ROSNOL AD-A1N25A/133-93 is a precision 50Ω RF adapter engineered to connect SMA Plug (Male) and N Jack (Female) interfaces. Supporting frequencies from DC to 12 GHz, it offers VSWR ≤ 1.15, insertion loss ≤ 0.04 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, and RF leakage ≥ 100 dB up to 1 GHz. These characteristics ensure stable, low-loss signal transmission for RF and microwave systems where performance and reliability are critical.
The N-side center contact is manufactured from beryllium copper and the SMA-side center contact from brass, both featuring gold plating over a non-magnetic nickel-phosphorus underplating for excellent conductivity and corrosion resistance. Brass bodies and coupling components with nickel plating provide durability and long-term mechanical performance, while PTFE insulators and silicone rubber gaskets enhance electrical reliability.
This adapter is widely used in wireless communications, broadcast systems, antenna installations, RF test equipment, industrial networking, satellite communications, and microwave laboratories. Its compact straight-body design, excellent electrical performance, and robust construction make it a reliable RF connectivity solution for demanding industry applications.
