SMA Jack (Female) to N Jack (Female) 4-Hole Flange Adapter, DC-11GHz VSWR 1.15

SMA Jack (Female) to N Jack (Female) Adapter | 4-Hole Flange Mount | Screw-Lock | Brass Body

The ROSNOL AD-A2N25A-PF/91-93 is a precision-engineered RF adapter designed for robust performance in high-frequency applications. This SMA-to-N flange mount adapter supports a frequency range from DC to 11 GHz with an impedance of 50 ohms, ensuring minimal signal loss and excellent return loss (VSWR ≤ 1.15). It offers superior electrical reliability with insulation resistance ≥ 5 GΩ and insertion loss ≤ 0.03√F (GHz) dB. Mechanical integrity is guaranteed through screw-lock coupling mechanisms on both sides, axial contact captivation ≥ 28 N, and a mating cycle rating of ≥ 500, making it ideal for demanding RF environments.

Constructed from high-quality materials, the center contacts are made of beryllium copper with gold plating over a non-magnetic nickel-phosphorus underlayer for optimal conductivity and corrosion resistance. The bodies are brass with gold plating on the SMA side and nickel plating on the N side, while PTFE insulators provide excellent dielectric properties. This combination ensures durability and stable performance under extreme conditions.

ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
