Many connector manufacturers publish recommended launches for their
connectors. You might want to check with your vendor...

Subject: [SI-LIST] Input Matching for SMA Connectors
Hi all,
I'm designing a test board that will have differential trace widths of 4 mil
and I want to connect SMA connectors to them, but I'm not sure what
connector would be suitable as the ones I've found have connector widths
that are neither equal to or smaller than the trace widths, as well as the
recommended pad sizes are much larger. For an RF design I did at Uni, I
just added a quarter wave transformer to provide the matching at the
operating frequency; is it still possible to do this with a high-speed
design with a 200 ps rise time (5 GHz) signal?
Or can anyone recommended a way to connect VNA coaxial cables to a PCB with
trace widths around 4 mils, such that the Zo is maintained.
Thanks,
--
