Hi Achim:
SMA RF connectors have a very limited life (number of matings) until
they are worn out.
I don't think so. Yes, they're only rated for 500 cycles, but there's a
paper by a guy at Maury Microwave that I ran across when trying to get
statistics on the reflection coefficient variation, and he set up a
automated rig to mate/demate SMAs something like 10,000 times.
I suspect that there is a WIDE variation among mfrs in terms of life
performance and manufacturing precision.
the 3.5mm connector (sort of a precision, super SMA), is rated for 3000
cycles.
