Description
SMB Jack (Female) to SMB Plug (Male) T-Adapter | Snap-on | Brass Body
The ROSNOL ADT-S2S1S25A/11-911-11 is a precision SMB T-adapter that combines two female SMB jacks and one male SMB plug for RF signal distribution from DC to 4 GHz. It offers 50 Ω impedance, insulation resistance ≥1 mΩ, and working voltage up to 250 V rms. The snap-on coupling mechanism ensures quick engagement and supports ≥500 mating cycles for reliable performance.The male center contact is brass with 3 μinch gold plating over an 80 μinch nickel-phosphorus underlayer, while female contacts use beryllium copper with identical plating for superior conductivity. Bodies and coupling nuts are brass with gold plating, and PTFE insulators provide excellent dielectric stability.
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.
