Description
SMA Plug (Male) to MMCX Jack (Female) RF Adapter | Screw-lock & Snap-lock | Brass Body
The ROSNOL AD-A1MX25A/911-91 RF adapter connects SMA plug (male) to MMCX jack (female) interfaces, supporting 50 Ω impedance and operating from DC to 6 GHz. It offers VSWR ≤ 1.20 (≥20.8 dB return loss), insertion loss ≤ 0.05 × √F(GHz) dB, and insulation resistance ≥1 GΩ. With ≥500 mating cycles and axial captivation ≥27 N on both sides, it ensures secure mechanical engagement and low contact resistance.Both SMA and MMCX sides feature beryllium copper center contacts with gold plating over non-magnetic nickel-phosphorus underplating. The brass body is similarly plated, with PTFE insulation, silicone rubber gasket, and brass coupling nut.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services for materials, plating, and mechanical design are available to support specialized requirements across a wide range of RF and microwave applications.
