Description
BNC Plug (Male) to SMA Jack (Female) Adapter | Bayonet-Lock & Screw-Lock | Brass Body
The ROSNOL AD-B1A25A/133-91 adapter delivers high-performance connectivity for BNC and SMA connectors. Operating from DC to 4 GHz with 50 Ω impedance, it achieves VSWR ≤1.15 and insertion loss ≤0.05 × √F (GHz) dB. Electrical ratings include insulation resistance ≥5 GΩ, test voltage 1000 V RMS, and working voltage 400 V RMS. Designed for reliability, it supports ≥500 mating cycles with bayonet-lock and screw-lock coupling.The adapter features beryllium copper and brass center contacts with gold plating over nickel underplating for superior conductivity. Brass bodies and coupling nuts are plated for corrosion resistance, while PTFE insulators provide excellent dielectric strength. The design withstands temperatures from -65°C to +165°C for dependable performance.
