TNC Plug (Male) to SMA Jack (Female) Adapter, DC-18GHz VSWR 1.3

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

The ROSNOL AD-T1A25A/944-91 offers robust RF performance from DC to 18 GHz with 50 Ω impedance. It delivers VSWR ≤1.30 and insertion loss ≤0.1√F (GHz) dB for stable signal transmission. Electrical specifications include insulation resistance ≥5 GΩ, center contact resistance ≤3 mΩ (SMA) and ≤1.5 mΩ (TNC), and outer contact resistance ≤2 mΩ and ≤1 mΩ respectively. Rated for 1000 V RMS test voltage and 480 V RMS working voltage, it supports power handling up to 80 W at 2 GHz. Screw-lock coupling on both ends provides secure engagement, with ≥500 mating cycles and center contact captivation ≥28 N (TNC) and ≥27 N (SMA).

The adapter features beryllium copper 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.
