The Amphenol RF 901-144-8RFX is a 50 Ohm SMA jack, female socket, built for signal paths up to 18 GHz. Threaded coupling locks the mate — no vibration loosens this connection on a test cable or a panel feedthrough.
What 100 Mating Cycles Means for Your Application
The 100-cycle rating is the weak spot on this part compared to the stainless-steel sibling (901-144, which carries 500 cycles). On a bench-top test fixture or a production test head that sees daily reconnection, 100 cycles means the gold-on-beryllium-copper centre contact wears through to the base metal sooner. For a one-time panel install or a cable assembly that mates once and stays, 100 cycles is fine. If the connector lives on a portable instrument cable that gets plugged and unplugged dozens of times a week, the 500-cycle stainless version is the better BOM line.
