Description
SMA Jack (Female) to BMA Jack (Female) RF Adapter | Screw-Lock & Slide-On | Stainless Steel Body
The ROSNOL AD-A2BA25A/9X-9X RF adapter connects SMA jack (female) to BMA jack (female), supporting DC to 18 GHz operation with 50-ohm impedance. Electrical performance includes VSWR ≤ 1.15 (≥ 23.15 dB return loss), insertion loss ≤ 0.04 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. It withstands test voltage of 1000 V rms and working voltage of 335 V rms, with RF leakage ≥ 85 dB up to 1 GHz. Mechanical design features screw-lock coupling for SMA and slide-on for BMA, with mating cycles of 500 and 1000 respectively, and recommended torque of 0.9 Nm for SMA.Premium materials ensure durability: beryllium copper center contacts with gold plating over nickel-phosphorus underlayer, stainless steel bodies with passivated finish, and PTFE insulators for excellent dielectric performance. This adapter is mechanically compatible with 3.5 mm and 2.92 mm interfaces on the SMA side and OSP/RPC-SP on the BMA side.
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.
