The 901-2GA200000AE: It sits in the 901-2G series of standard SMA connectors. The 50 Ohm impedance matches the common RF system impedance, and the 18 GHz maximum frequency covers L-band through Ku-band applications — think satellite comms, test equipment, and microwave backhaul where the signal path needs a clean launch off the panel. The threaded fastening provides a vibration-resistant mate. The gold body finish and stainless steel body material resist corrosion.
Sizing the Signal Path
The 18 GHz ceiling means it handles the full bandwidth of common SMA applications; above 18 GHz the VSWR rises and the connector becomes a mismatch. For a 6 GHz Wi-Fi or 10 GHz radar front end, this jack has headroom to spare. 500 mating cycles is a high figure for a threaded SMA — the gold-over-beryllium copper centre contact and gold body finish keep contact resistance stable through repeated connect-disconnect cycles in field-service or test-bench use.
