The 901-2GF705590AE: The 50 Ohm impedance is non-negotiable for any 50 Ohm system — this jack matches standard 50 Ohm cable assemblies and PCB launches without an impedance step. The 18 GHz max frequency covers S-band through Ku-band, making it suitable for microwave test points, satellite ground equipment, and radar subsystems. The threaded fastening gives a vibration-resistant mate that won't back off under mechanical shock, unlike a push-on or bayonet coupling. With 500 mating cycles on the gold-over-beryllium copper centre contact, this jack is rated for field-service life where the connector sees regular disconnect and reconnect — not a one-time install.
Panel mount with a flange means the jack bolts to the chassis or panel face, not the PCB edge. You'll need to solder the centre conductor and the shield braid to the respective cups or posts. The body finish is gold over stainless steel, which gives a low-resistance ground path and resists corrosion in humid or salt-spray environments.
