Description
SMA Jack (Female) to SMC Jack (Female) Straight RF Adapter | Screw-Lock | Brass Body
The ROSNOL AD-A2MC25A/91-91 straight RF adapter connects SMA jack (female) to SMC jack (female), supporting DC to 10 GHz operation with 50-ohm impedance. Electrical performance includes VSWR ≤ 1.3 (≥ 17.69 dB return loss), insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 1 GΩ. It withstands 750 V rms test voltage and offers RF leakage ≥ 90 dB up to 1 GHz. Mechanical design features screw-lock coupling on both sides, with mating cycles of 500 minimum and recommended torque of 0.8–1.1 Nm for SMA.Constructed for reliability, the adapter uses beryllium copper center contacts with gold plating over nickel-phosphorus underlayer, brass bodies with gold finish, and PTFE insulators for superior dielectric properties. This design ensures robust performance for high-frequency RF 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. Customization for materials, plating, and mechanical design is available to meet specialized
