Description
MMCX Plug (Male) to SMA Jack (Female) | Straight Design | Snap-Lock & Screw-Lock | Brass Body
The ROSNOL AD-MX1A25A/91-91 is engineered for RF systems requiring stable performance up to 6 GHz with 50 ohm impedance. It delivers a VSWR of ≤1.20 and insertion loss of ≤0.05 × √F GHz, ensuring optimal signal integrity. Electrical ratings include insulation resistance ≥1 GΩ, test voltage 750 Vrms, working voltage 335 Vrms, and contact current up to 1.5 A DC. Snap-lock coupling on the MMCX side and screw-lock on the SMA side provide secure engagement, with mechanical durability exceeding 500 mating cycles.Materials and plating are optimized for conductivity and durability. Both sides feature beryllium copper center contacts with gold plating over nickel-phosphorus underplating, brass bodies gold plated, and PTFE insulators for dielectric stability. The adapter operates within a temperature range of −55°C to +155°C.
ROSNOL’s RF adapters deliver consistent quality and cost efficiency, making them a reliable alternative to leading European and American brands. All ROSNOL components are manufactured in ISO 9001 certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to meet specialized interconnect requirements.
