Description
SMA Jack (Female) to BMA Jack (Female) RF Adapter | Screw-Lock & Slide-On | Stainless Steel Body
The ROSNOL AD-A2BA25A/1X-1X RF adapter offers secure connectivity between SMA jack (female) and BMA jack (female), operating from DC to 22 GHz with 50-ohm impedance. It achieves VSWR ≤ 1.3 (≥ 17.69 dB return loss), insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. Test voltage is rated at 1000 V rms for both sides, with working voltage of 480 V rms (SMA) and 335 V rms (BMA). Mechanical integrity includes screw-lock coupling for SMA and slide-on for BMA, axial captivation ≥ 27 N, and recommended torque of 0.8–1.1 Nm for SMA.Constructed for reliability, the adapter uses brass center contacts with gold plating over nickel-phosphorus underlayer, stainless steel bodies with passivated finish, and PTFE insulators for superior dielectric properties. It 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.
