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/144-H4 is designed for RF systems requiring robust performance from DC to 18 GHz with 50 Ω impedance. It delivers VSWR ≤1.30 and insertion loss ≤0.04√F (GHz) dB for superior signal integrity. Electrical ratings 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. The adapter withstands 1000 V RMS test voltage and 480 V RMS working voltage, supporting up to 80 W at 2 GHz. Screw-lock coupling ensures secure engagement, with ≥500 mating cycles and center contact captivation ≥27 N on both ends.

The center contacts are phosphor bronze and brass with gold plating over nickel-phosphorus underplating for durability and conductivity. Bodies and coupling nuts are brass with copper-tin-zinc alloy finish, while insulators are PTFE for excellent dielectric performance. A silicone rubber gasket enhances environmental sealing. The adapter operates reliably from -55°C to +155°C, meeting the demands of harsh environments.

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.
