Description
SMA Snap-On Plug (Male) to SMA Jack (Female) Adapter | Snap-Lock & Screw-Lock | Brass Body
The ROSNOL AD-AQ1A25A/991-91 adapter delivers high-performance connectivity for SMA snap-on and SMA connectors. Operating from DC to 18 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 350 V RMS. Designed for reliability, it supports ≥500 mating cycles with snap-lock and screw-lock coupling.The adapter features beryllium copper center contacts and brass bodies with gold plating over nickel-phosphorus underplating. PTFE insulators and silicone rubber gaskets provide excellent dielectric strength, while brass coupling nuts ensure mechanical stability. The design withstands temperatures from -65°C to +165°C for dependable performance.
