QI am using Evaluation Board of ADF4350. And want to know the permittivity and
the dielectric materials of the EVB.
AWe 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
Rogers material has a permittivity constant 3.55. FR4 has a constant of 4.8.
