Description
SMA Plug (Male) to Mini UHF Jack (Female) Straight RF Adapter | Screw-Lock | Brass Body
The ROSNOL AD-A2MU25A/91-94 straight RF adapter connects SMA plug (male) to Mini UHF 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 ≤ 5 mΩ (Mini UHF), and outer contact resistance ≤ 2 mΩ (SMA) and ≤ 3 mΩ (Mini UHF). It withstands 1000 V rms test voltage and ensures reliable signal transmission for low-frequency applications.Premium materials include beryllium copper center contacts with gold plating over nickel-phosphorus underlayer, brass bodies with gold finish, and PTFE insulators for excellent dielectric performance. Mechanical design features screw-lock coupling on both sides, with mating cycles of 500 minimum and recommended torque of 0.8–1.1 Nm for SMA.
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.
