Description
BNC Plug (Male) to SMB Plug (Male) Adapter | Straight Design | Bayonet-Lock & Snap-Lock | Brass Body
The ROSNOL AD-B1S15A/944-911 adapter delivers high-performance connectivity for BNC and SMB connectors. Operating from DC to 4 GHz with 50 Ω impedance, it achieves VSWR ≤1.35 and insertion loss ≤0.05 × √F (GHz) dB. Electrical ratings include insulation resistance ≥5 GΩ and robust mechanical coupling. Designed for reliability, it supports ≥500 mating cycles with bayonet-lock and snap-lock mechanisms.The adapter features beryllium copper center contacts with gold plating over nickel-phosphorus 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.
