SMA Jack, 50 Ohm, 18 GHz — Panel-Mount Bulkhead Entry
The 901-5GA200000AE: This is a full-bandwidth SMA — the 18 GHz ceiling means it handles the entire common SMA range without rolling off, so it suits both legacy 6 GHz gear and modern 18 GHz test setups. The panel-mount flange secures the connector to a bulkhead or chassis wall, taking the mechanical load off the solder cup termination during cable handling. Gold-over-beryllium copper gives the center pin spring memory — it returns to shape after repeated mating, which is what supports the 500-cycle rating. The dielectric is PTFE, the standard low-loss material for RF connectors up through Ku-band. The threaded fastening type (SMA standard) ensures a vibration-resistant mate when torqued to spec.
Termination and Mounting — Solder Cup, Flange, Panel
Termination is solder cup — the centre contact and shield both solder to the cable. Solder cup is field-serviceable: a technician can replace a damaged cable end without a crimp tool, which matters for test cables and field repairs. Mounting is panel mount with a flange. The flange has clearance holes for M2.5 or #4 screws (typical) and orients the connector face perpendicular to the panel. This is a bulkhead-style install — the jack stays fixed while the mating plug threads on. For a single-port connector, the flange alignment matters: if the panel cutout is off by more than 0.1 mm, the threads bind during mate.
