Description
SMA Jack (Female) to BNC Jack (Female) RF Adapter | Screw-Lock & Bayonet-Lock | Stainless Steel Body
The ROSNOL AD-A2B25A/9X-9X RF adapter combines SMA jack (female) and BNC jack (female) interfaces for robust connectivity in RF systems. Operating from DC to 6 GHz with 50-ohm impedance, it achieves VSWR ≤ 1.15 up to 4 GHz and ≤ 1.2 up to 6 GHz, insertion loss ≤ 0.04 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. RF leakage performance supports up to 80 W at 2 GHz. Mechanical features include screw-lock coupling on the SMA side and bayonet-lock on the BNC side, with mating cycles of 500 minimum and torque range of 0.8–1.1 Nm for SMA.Constructed for durability, the center contacts are beryllium copper with gold plating over a nickel-phosphorus underlayer. Both SMA and BNC bodies are stainless steel with passivated finish, and PTFE insulators provide excellent dielectric properties.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across RF and microwave systems. Designed to meet stringent high-frequency requirements, ROSNOL adapters provide a cost-effective alternative to leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. Customization for materials, plating, and mechanical design is available to meet specialized interconnect needs.
