Hi, experts,
I am new to this field and I get a question for you guys. I saw a formula
saying BW=0.35/Trise. So for a TDR module with 30ps rise time I should get a
BW of 11.67GHz. Am I correct on this? I saw from a TDR spec that for 30ps
rise time, the BW was 20GHz. That confused me.

Thanks.
Kevin
