We routinely do boards with signal frequencies in the 2.0 to 10GHtz
range. I ALWAYS use rounded corners! The trace width does not change in
an arc but it does with mitered or right angle corners.

Subject: [DC] Another RF Question??


Which trace geometry is best suited for High-Speed RF signals...
Rounded traces, or Square corners?
I've heard the theory that if you use corners...
the current travels straight, then turns to it's location, but any
EMI/cross-talk noise will continue to try to travel straight and "fall
of the edge"?  What's your theory on this?

Inquiring minds want to know...

Thanks,
Kitty
