SMA Jack (Female) to FME Jack (Female) Straight RF Adapter | Screw-Lock | Brass Body
The ROSNOL AD-A2E25A/94-94 straight RF adapter connects SMA jack (female) to FME jack (female), supporting DC to 2.5 GHz operation with 50-ohm impedance. Electrical performance includes insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ (SMA) and ≤ 10 mΩ (FME), and outer contact resistance ≤ 2 mΩ (SMA) and ≤ 1.5 mΩ (FME). It withstands 1000 V rms test voltage and offers reliable signal transmission for low-frequency applications.
Constructed for durability, the adapter uses beryllium copper center contacts with gold plating over nickel-phosphorus underlayer, brass bodies with copper-tin-zinc alloy plating, and PTFE insulators for superior dielectric performance. Mechanical integrity includes screw-lock coupling on both sides, with mating cycles of 500 for SMA and 300 for FME.
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.
