Description
SMA Bulkhead Jack (Female) to BMA Jack (Female) RF Adapter | Screw-Lock & Slide-On | Stainless Steel Body
The ROSNOL AD-A2BA25A-BH/9X-9X bulkhead RF adapter connects SMA jack (female) to BMA jack (female), supporting DC to 18 GHz operation with 50-ohm impedance. Electrical performance includes VSWR ≤ 1.14 (≥ 23.69 dB return loss), insertion loss ≤ 0.06 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. It withstands 1000 V rms test voltage and offers RF leakage of -60 dB at 2.3 GHz. Mechanical design features screw-lock coupling for SMA and slide-on for BMA, with mating cycles of 500 minimum 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. Additional components include compression springs and retaining rings for secure bulkhead installation.
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.
