Description
SMA Plug (Male) to BNC Jack (Female) Adapter | Screw-lock & Bayonet-lock | Brass Body
The ROSNOL AD-A1B25A/H33-H3 is a precision-engineered RF adapter designed for SMA to BNC interconnection, supporting DC to 6 GHz operation. It offers 50 Ω impedance, VSWR ≤1.2 (≥20.83 dB), and 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 nickel-plated brass body and phosphor bronze center contacts, the adapter features 3 µinch gold plating over non-magnetic nickel-phosphorus underplating. PTFE insulators and silicone rubber gaskets ensure reliable 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.
