What's the right PCB substrate for USB4?
Some colleagues are working on a project that leverages USB4 and looking to design their own PCB. The insertion loss limits are pretty clear in the USB4 standard (see image), which leaves routing, trace sizing, and the substrate as ways to mitigate insertion loss.
What PCB substrate materials do you recommend to combat insertion loss in USB4 systems? Also, does a 2-layer design have a snowball's chance of passing EMC testing?
I hope some of the PCB and hardware engineers in server - @Petr Dvořák @pallavaggarwal @Joseph Ogbonna - may be able to answer this question. Thanks.
