Description
SMB Plug (Male) to SMA Jack (Female) | L-Adapter | Gold-Plated Brass Body
The ROSNOL ADL-S1A25A/911-91 is a compact SMB to SMA L-adapter designed for RF systems operating up to 4 GHz. Featuring snap-lock and screw-lock coupling mechanisms, it supports ≥500 mating cycles per side, axial captivation ≥10 N, and torque rating up to 1.7 Nm on the SMA side. Electrical performance includes 50 Ω impedance, VSWR ≤1.09 (≥27 dB), insertion loss ≤0.05×√F(GHz) dB, and RF leakage ≥55 dB up to 1 GHz.Constructed with a gold-plated brass body and coupling nut, the ADL-S1A25A/911-91 features beryllium copper center contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, PTFE insulators, and a robust mechanical structure. It performs reliably across a temperature range of -55°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.
