Description
SMA Jack (Female) to N R/P Jack (Female) Straight RF Adapter | Screw-Lock | Brass Body
The ROSNOL AD-A2N75A/91-H3 straight RF adapter offers secure connectivity between SMA jack (female) and N Reverse Polarity jack (female), operating from DC to 12 GHz with 50-ohm impedance. It achieves VSWR ≤ 1.15 (≥ 23.13 dB return loss), insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. Test voltage is rated at 1000 V rms, with working voltage of 480 V rms and RF leakage ≥ 100 dB up to 1 GHz. Mechanical integrity includes screw-lock coupling on both sides, axial captivation ≥ 28 N, and recommended torque of 0.8–1.1 Nm for SMA.Constructed for reliability, the adapter uses beryllium copper and phosphor bronze center contacts with gold plating over nickel-phosphorus underlayer, brass bodies with nickel finish, and PTFE insulators for superior dielectric properties. This design ensures robust performance for high-frequency RF environments.
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.
