Description
SMA Plug (Male) to TNC Jack (Female) Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1T25A/911-94 RF adapter provides dependable connectivity with 50 Ω impedance and DC to 11 GHz frequency range. It maintains VSWR ≤1.20 (≥20.83 dB) and insertion loss ≤0.05 × √F (GHz) dB for consistent signal quality. The screw-lock coupling ensures secure engagement, and the adapter operates from -65°C to +165°C for robust environmental performance.Material construction includes phosphor bronze center contacts with gold plating (nickel underplated), brass body with gold plating (nickel underplated) on the SMA side, and brass body with copper-tin-zinc alloy on the TNC side. Both interfaces use PTFE insulators, silicone rubber gasket, and gold-plated brass coupling nut for durability and corrosion resistance.
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.
