Description
SMA Plug (Male) to BNC Plug (Male) Adapter | Screw-lock & Bayonet-lock | Brass Body
The ROSNOL AD-A1B15A/911-933 is a precision SMA to BNC adapter designed for RF systems up to 6 GHz. It offers 50 Ω impedance, VSWR ≤1.15 (≥23.13 dB) up to 4 GHz and ≤1.2 (≥20.83 dB) from 4–6 GHz, with insertion loss ≤0.05 × √F (GHz) dB. Mechanical specifications include screw-lock coupling on the SMA side and bayonet-lock on the BNC side, ≥500 mating cycles, axial captivation ≥27 N, and torque range of 0.8–1.1 Nm.Constructed with a brass body and coupling nut, the adapter features beryllium copper center contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. PTFE insulators and silicone rubber gaskets ensure robust dielectric and sealing performance.
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.
