Description
SMA Plug (Male) to SMA Snap-on Jack (Female) Adapter | Screw-lock & Snap-lock | Stainless Steel Body
The ROSNOL AD-A1AQ25A/99X-9X is a precision-engineered straight adapter featuring SMA male to SMA snap-on female connectors, designed for RF systems operating up to 18 GHz. It offers 50 Ω impedance, VSWR ≤1.2 (≥20.8 dB), and insertion loss ≤0.05 × √F (GHz) dB. With insulation resistance ≥5 GΩ and center/outer contact resistance ≤3 mΩ, this adapter ensures stable signal transmission. Mechanical specifications include screw-lock and snap-lock coupling mechanisms, ≥500 mating cycles on both ends, and axial captivation ≥27 N.Constructed with passivated stainless steel and gold-plated beryllium copper bodies, 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 provide excellent 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.
