TNC Plug (Male) to BNC Jack (Female) Adapter, DC-4GHz VSWR 1.15

TNC Plug (Male) to BNC Jack (Female) | Straight Design | Screw-Lock & Bayonet-Lock | Brass Body

The ROSNOL AD-T1B25A/133-H3 is a precision RF adapter designed for systems operating from DC to 4 GHz with 50 Ω impedance. It delivers VSWR ≤1.15 (≥23.1 dB return loss) and insertion loss ≤0.05√F (GHz) dB for excellent signal integrity. Electrical ratings include insulation resistance ≥5 GΩ, center contact resistance ≤1.5 mΩ on both sides, and outer contact resistance ≤1 mΩ. The adapter withstands 1500 V RMS test voltage and 400 V RMS working voltage, supporting 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 on both ends.

The center contacts are brass and phosphor bronze 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 properties. A silicone rubber gasket enhances environmental sealing. Operating temperature ranges from -65°C to +165°C for dependable performance 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.
