Description
TNC Plug (Male) to SMA Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-T1A25A/133-91 is a precision adapter for RF and microwave systems, operating from DC to 11 GHz with 50 Ω impedance. It ensures VSWR ≤1.25 (≥19.08 dB return loss) and insertion loss ≤0.1√F (GHz) dB for stable signal integrity. Electrical ratings include insulation resistance ≥5 GΩ, center contact resistance ≤3 mΩ (SMA) and ≤1.5 mΩ (TNC), outer contact resistance ≤2 mΩ and ≤1 mΩ respectively. The adapter withstands 1000 V RMS test voltage and 480 V RMS working voltage, with power handling up to 80 W at 2 GHz. Both ends feature screw-lock coupling with center contact captivation ≥27 N and mechanical durability of ≥500 mating cycles.The center contacts are beryllium copper and brass with gold plating over nickel-phosphorus underplating for superior conductivity and corrosion resistance. Bodies and coupling nuts are brass with nickel finish, while insulators are PTFE for excellent dielectric performance. A silicone rubber gasket enhances environmental sealing. The adapter operates reliably from -65°C to +165°C, ensuring durability in harsh conditions.
ROSNOL’s precision-engineered RF adapters deliver consistent performance across high-frequency applications. Manufactured in ISO 9001-certified facilities and fully compliant with RoHS and REACH, they provide a cost-effective alternative to leading European and American brands. Customization for materials, plating, and mechanical design is available to meet specialized requirements.
