Description
BNC Plug (Male) to SMA Jack (Female) Adapter | Bayonet-Lock & Screw-Lock | Brass Body
The ROSNOL AD-B1A25A/111-H1 adapter ensures reliable connectivity between BNC and SMA connectors for RF systems. Operating from DC to 4 GHz with 50 Ω impedance, it achieves VSWR ≤1.15 and insertion loss ≤0.04 × √F (GHz) dB. Electrical ratings include insulation resistance ≥5 GΩ, test voltage 1000 V RMS, and working voltage 400 V RMS. Designed for durability, it supports ≥500 mating cycles with bayonet-lock and screw-lock coupling mechanisms.The center contacts are phosphor bronze and brass with gold plating over nickel-phosphorus underplating for superior conductivity. Brass bodies feature gold plating, complemented by PTFE insulators and silicone rubber gaskets. The adapter withstands temperatures from -65°C to +165°C, ensuring dependable performance in demanding environments.
