I am using Evaluation Board of ADF4350. And want to know the permittivity and
the dielectric materials of the EVB.

 

We use Rogers 8 mils of 4003 dielectric material on the top and bottom of the
board for the RF traces, and FR4 in the middle for traces that aren’t as
critical.
Rogers material has a permittivity constant 3.55. FR4 has a constant of 4.8.
