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/H44-H4 RF adapter ensures robust connectivity for low-frequency systems with 50 Ω impedance and DC to 300 MHz frequency range. It delivers VSWR ≤1.20 (≥20.83 dB) and insertion loss ≤0.05 × √F (GHz) dB, maintaining signal integrity under demanding conditions. Additional features include insulation resistance ≥5 GΩ, center contact resistance ≤3 mΩ (SMA) and ≤5 mΩ (UHF), and mechanical endurance of 500 mating cycles. Operating temperature spans -65°C to +165°C, and the screw-lock coupling mechanism guarantees secure engagement.

Material construction includes phosphor bronze center contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, brass body with copper-tin-zinc alloy finish, PTFE insulator, silicone gasket, and brass coupling nut for enhanced durability. The UHF side uses similar phosphor bronze contacts and brass body with copper-tin-zinc alloy plating for corrosion resistance and long-term reliability.
