MCX Plug (Male) to SMA Jack (Female) Adapter, DC-6GHz VSWR 1.15

MCX Plug (Male) to SMA Jack (Female) | Straight Design | Snap-Lock & Screw-Lock | Brass Body

The ROSNOL AD-M1A25A/9H-91 is engineered for high-frequency RF systems, supporting DC to 6 GHz with a 50 ohm impedance. It delivers a VSWR of ≤1.15 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 RF leakage ≥100 dB up to 1 GHz. Snap-lock coupling on the MCX side and screw-lock on the SMA side provide secure engagement, with recommended torque of 0.80 to 1.10 Nm for the SMA side. Mechanical durability exceeds 500 mating cycles.

Materials and plating are optimized for conductivity and durability. The SMA side uses beryllium copper center contacts with gold plating over nickel-phosphorus underplating, brass body gold plated, and PTFE insulator. The MCX side features beryllium copper center contacts and phosphor bronze body with the same gold-over-nickel-phosphorus plating stack, and PTFE insulator. The adapter maintains stable performance from −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.
