SMA Jack (Female) to MHFI Jack (Female) Straight RF Adapter | Screw-Lock & Slide-Lock | Brass Body
The ROSNOL AD-A2MHFI25A-BH/91-91 straight RF adapter connects SMA jack (female) to MHFI jack (female), supporting DC to 10 GHz operation with 50-ohm impedance. Electrical performance includes VSWR ≤ 1.4 (≥ 15.6 dB return loss), insulation resistance ≥ 5 GΩ, and center contact resistance ≤ 3 mΩ. It withstands 1000 V rms test voltage for robust signal integrity. Mechanical design features screw-lock coupling for SMA and slide-lock for MHFI, 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, brass bodies with gold finish, and PTFE insulators for excellent dielectric performance. Silicone rubber gaskets and brass coupling nuts enhance mechanical stability for demanding 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.
