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,
--
