Description
SMA Jack (Female) to N Jack (Female) Bulkhead RF Adapter | Screw-Lock | Brass Body
The ROSNOL AD-A2N25A-BH/91-93 bulkhead RF adapter connects SMA jack (female) to N jack (female), supporting DC to 11 GHz operation with 50-ohm impedance. Electrical performance includes VSWR ≤ 1.20 (≥ 20.8 dB return loss), insertion loss ≤ 0.03 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. It withstands 1000 V rms test voltage and offers RF leakage ≥ 100 dB up to 1 GHz. Mechanical design features screw-lock coupling on both sides, with mating cycles of 500 minimum and recommended torque of 0.7–1.1 Nm for SMA and N.Premium materials include beryllium copper center contacts with gold plating over nickel-phosphorus underlayer, brass bodies with nickel finish, and PTFE insulators for excellent dielectric performance. Silicone rubber gaskets and fastening hardware provide additional sealing and mechanical stability for rugged applications.
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.
