Description
SMA Jack (Female) to BNC Jack (Female) 4-Hole Panel RF Adapter | Screw-Lock & Bayonet-Lock | Stainless Steel Body
The ROSNOL AD-A2B25A-PF/9X-9X 4-hole panel RF adapter connects SMA jack (female) to BNC jack (female), supporting DC to 4 GHz operation with 50-ohm impedance. Electrical performance includes VSWR ≤ 1.20 (≥ 20.83 dB return loss), insertion loss ≤ 0.04 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. Power handling reaches 80 W at 2 GHz, with test voltage of 1000 V rms and working voltage of 400 V rms. Mechanical design features screw-lock coupling for SMA and bayonet-lock for BNC, with mating cycles of 500 minimum and recommended torque of 0.8–1.1 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. The 4-hole panel design provides secure mounting for high-reliability RF systems.
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.
