Hi,
In the reference design for the IWR1443BOOST, the layer stackup calls for Rogers 4835 with a process dielectric constant of 3.48. After reading the datasheet for the Rogers material and consulting with our board shop, it seems that the correct constant should be the design constant specified as 3.66.
Is this an oversight in the design of the eval board or is there a reason to use the 3.48 dielectric contstant?
Thanks,
Kevin
