Description
SMA Jack (Female) to BNC Jack (Female) RF Adapter | Screw-Lock & Bayonet-Lock | Brass Body
The ROSNOL AD-A2B25A/91-94 RF adapter connects SMA jack (female) to BNC jack (female), supporting DC to 6 GHz operation with 50-ohm impedance. Electrical performance includes 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 supports up to 80 W at 2 GHz. Mechanical design features screw-lock coupling for SMA and bayonet-lock for BNC, with mating cycles of 500 minimum and torque range of 0.8–1.1 Nm for SMA.Premium materials ensure reliability: beryllium copper center contacts with gold plating over nickel-phosphorus underlayer, brass bodies with gold plating for SMA and copper-tin-zinc alloy for BNC, and PTFE insulators for superior dielectric performance.
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.
