SMA Plug (Male) to UHF Jack (Female) Adapter, DC-300MHz VSWR 1.20

SMA Plug (Male) to UHF Jack (Female) Adapter | Screw-lock | Brass Body

The ROSNOL AD-A1U25A/H33-H3 RF adapter provides dependable performance for low-frequency applications with 50 Ω impedance and DC to 300 MHz operating range. It achieves VSWR ≤1.20 (≥20.83 dB) and insertion loss ≤0.05 × √F (GHz) dB, ensuring stable signal transmission. Additional specifications include insulation resistance ≥5 GΩ, center contact resistance ≤3 mΩ (SMA) and ≤5 mΩ (UHF), and durability with 500 mating cycles. The adapter operates within -65°C to +165°C and features screw-lock coupling for secure engagement.

The SMA side uses phosphor bronze contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, brass body with nickel finish, PTFE insulator, silicone gasket, and nickel-plated brass coupling nut. The UHF side includes phosphor bronze contacts with identical plating, brass body with nickel finish, and PTFE insulation for corrosion resistance and long-term reliability.
