SMA R/P Plug (Male) to TNC Jack (Female) Adapter, DC-11GHz VSWR1.20

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

The ROSNOL AD-A5T25A/H33-H3 adapter provides reliable interconnection between SMA reverse-polarity and TNC connectors for RF and microwave systems. Operating from DC to 11 GHz with a 50 Ω impedance, it achieves VSWR ≤1.20, ensuring minimal signal reflection and stable performance. Electrical parameters include insertion loss ≤0.05 × √F (GHz) dB, insulation resistance ≥5 GΩ, and center contact resistance ≤3 mΩ on the SMA side and ≤1.5 mΩ on the TNC side. Rated for 1000 V RMS test voltage and 480 V RMS working voltage, this adapter supports ≥500 mating cycles with screw-lock coupling on both ends and axial contact captivation ≥27 N.

Constructed for durability, the center contacts are phosphor bronze with gold plating over nickel-phosphorus underplating for superior conductivity and corrosion resistance. The bodies and coupling nuts are brass with nickel plating, while PTFE insulators and silicone rubber gaskets ensure excellent dielectric strength. The adapter withstands temperatures from -65°C to +165°C, delivering long-term reliability in demanding environments.

ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
