Description
SMA Plug (Male) to SMA Jack (Female) L-Adapter | Screw-lock | Gold-Plated Brass Body
The ROSNOL ADL-A1A25D/111-111 is a high-frequency SMA male-to-female L-adapter designed for RF systems operating up to 18 GHz. It features a screw-lock coupling mechanism with ≥ 500 mating cycles, VSWR ≤ 1.15, and insertion loss ≤ 0.03 × √F(GHz) dB. The adapter supports up to 200 W at 2 GHz and ensures RF leakage ≥ 100 dB up to 1 GHz. Mechanical robustness includes coupling nut retention ≥ 270 N and axial captivation ≥ 27 N.Constructed with brass bodies and coupling nuts, all gold-plated with 3 µinch over 80 µinch non-magnetic nickel-phosphorus underplating, the adapter includes brass center contacts and PTFE insulators. Silicone rubber gaskets ensure stable dielectric performance across −65°C to +155°C.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services for materials, plating, and mechanical design are available to support specialized requirements across a wide range of RF and microwave applications.
