Description
SMA Plug (Male) to BMA Plug (Male) Adapter | Screw-lock & Slide-on | Stainless Steel Body
The ROSNOL AD-A1BA15A/1XX-1X is a precision RF adapter designed for SMA to BMA interconnection, supporting DC to 26.5 GHz operation. It offers 50 Ω impedance, VSWR ≤1.15 (≥23.15 dB), and insertion loss ≤0.04 × √F (GHz) dB. Mechanical specifications include screw-lock coupling on the SMA side and slide-on on the BMA side, ≥500 and ≥1000 mating cycles respectively, axial captivation ≥27 N, and torque rating of 0.9 Nm.Constructed with passivated stainless steel body and coupling nut, the adapter features brass 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.
