The ROSNOL AD-T1B25A/H44-H4 offers reliable RF performance from DC to 4 GHz with 50 Ω impedance. It achieves VSWR ≤1.20 and insertion loss ≤0.05√F (GHz) dB for stable signal transmission. Electrical specifications include insulation resistance ≥5 GΩ, center contact resistance ≤1.5 mΩ on both sides, and outer contact resistance ≤1 mΩ. Rated for 1500 V RMS test voltage and 400 V RMS working voltage, it supports power handling up to 80 W at 2 GHz. Coupling mechanisms include screw-lock on the TNC side and bayonet-lock on the BNC side, with ≥500 mating cycles and center contact captivation ≥15 N.
The adapter features phosphor bronze contacts with gold plating over nickel-phosphorus underplating for optimal conductivity. Bodies and coupling nuts are brass with copper-tin-zinc alloy finish, and insulators are PTFE for excellent dielectric properties. A silicone rubber gasket ensures environmental sealing. Operating temperature ranges from -65°C to +165°C for dependable performance.
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.
