SMA Jack (Female) to Precision TNC Jack (Female) Adapter | Screw-Lock | Stainless Steel Body
The ROSNOL AD-A2PCT25B/9X-9X is a high-performance RF adapter designed to connect SMA Jack (Female) and Precision TNC Jack (Female) interfaces in 50 Ω systems. Operating from DC to 18 GHz, it achieves VSWR ≤ 1.25, insertion loss ≤ 0.1 × √F (GHz) dB, and insulation resistance of at least 5 GΩ. Threaded coupling mechanisms and a minimum of 500 mating cycles ensure dependable mechanical engagement and long-term RF performance.
The center contacts are manufactured from beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplating. Beryllium copper provides outstanding electrical conductivity, resilience, and wear resistance, while gold plating maintains stable contact performance. Both connector bodies are manufactured from stainless steel with passivated surfaces. Stainless steel delivers excellent structural strength and corrosion resistance, while passivation enhances environmental protection. PTFE insulators contribute low dielectric loss and stable electrical characteristics across a wide frequency range.
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.
