SMA Jack (Female) to MCX Jack (Female) Straight RF Adapter | Screw-Lock & Snap-Lock | Brass Body
The ROSNOL AD-A2M25A/91-91 straight RF adapter connects SMA jack (female) to MCX jack (female), supporting DC to 6 GHz operation with 50-ohm impedance. Electrical performance includes VSWR ≤ 1.20 (≥ 20.8 dB return loss), insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 1 GΩ. It withstands 750 V rms test voltage and supports a maximum contact current of 1.5 A DC. Mechanical design features screw-lock coupling for SMA and snap-lock for MCX, with mating cycles of 500 minimum and recommended torque of 0.8–1.1 Nm for SMA.
Premium materials ensure durability: beryllium copper center contacts with gold plating over nickel-phosphorus underlayer, brass bodies with gold finish, and PTFE insulators for excellent dielectric performance. This adapter is ideal for secure and reliable RF connections in high-frequency systems.
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.
