Description
SMA Plug (Male) to TNC Jack (Female) Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1T25A/911-93 adapter offers superior RF performance with 50 Ω impedance and DC to 11 GHz frequency coverage. It achieves VSWR ≤1.20 (≥20.83 dB) and insertion loss ≤0.05 × √F (GHz) dB, ensuring minimal signal degradation. Additional specifications include insulation resistance ≥5 GΩ, center contact resistance ≤3 mΩ (SMA) and ≤1.5 mΩ (TNC), and power handling up to 80 W at 2 GHz. The adapter withstands -65°C to +155°C and supports up to 500 mating cycles with recommended torque of 0.9 Nm (SMA) and 0.46–0.69 Nm (TNC).The SMA interface uses beryllium copper contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, brass body with similar plating, PTFE insulator, silicone gasket, and gold-plated brass coupling nut. The TNC side features beryllium copper contacts with identical plating, brass body with nickel finish, and PTFE insulation.
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.
