At 2.5 MHz the attenuation constant is an important factor. If line lengths
are short, I believe FR-4 can be used within the constraints mentioned.

HI All,

i am doing a 2.5Ghz PCB design. i was wondering whether FR4 material
is sufficient for such high speed signals? or i should look at some
other material for these desings? and if FR4 is sufficient is there any
special care i have to take (other than impedance matching and differential
routings)

thanks in advance,
