Description
SMA Jack (Female) to MMBX Jack (Female) Straight RF Adapter | Screw-Lock & Snap-Lock | Brass Body
The ROSNOL AD-A2BX25A/91-91 straight RF adapter connects SMA jack (female) to MMBX jack (female), supporting DC to 12.4 GHz operation with 50-ohm impedance. Electrical performance includes VSWR ≤ 1.08 (≥ 28.3 dB return loss), insertion loss ≤ 0.42 dB, and insulation resistance ≥ 1 GΩ. It withstands 500 V rms test voltage and offers robust signal integrity for high-frequency applications.Premium materials ensure reliability: beryllium copper center contacts with gold plating over nickel-phosphorus underlayer, brass bodies with gold finish, and PTFE insulators for excellent dielectric properties. Mechanical design features screw-lock coupling for SMA and snap-lock for MMBX, with mating cycles of 500 minimum for each interface.
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.
