Description
SMA Plug (Male) to MMCX RP Plug (Male) RF Adapter | Screw-lock & Snap-lock | Stainless Steel Body
The ROSNOL AD-A1MX55A/9XX-9X RF adapter is designed for reverse-polarity MMCX plug (male) to SMA plug (male) connections, supporting 50 Ω impedance and operating up to 6 GHz. It features 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, it ensures reliable performance in demanding RF environments.Constructed with stainless steel bodies and passivated finish, both SMA and MMCX sides include beryllium copper contacts with gold plating over non-magnetic nickel-phosphorus underplating, PTFE insulation, silicone rubber gasket, and stainless steel 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.
