AWR1642BOOST: AWR1642BOOST: EVM stack up question

cheng nai how
Prodigy 10 points
Part Number: AWR1642BOOST

I found two different AWR1642BOOST EVM Board resource as followings from the e2e and ti website
1. www.ti.com/.../spracg5.pdf
2. www.ti.com/.../sprr261

From these sheets, there have slight difference stackups at thickness of some layers. Which one should I comply with since I assume RF signal on the top of RO4835 have exactly definition on simulation else.

    Hello Cheng,
    Are you referring to slight difference in the processed thickness of the L1 copper? That would not make much difference in the impedance . Either of the ones can be used. Different manufactures will have a slightly different copper thickness due to processing differences. But both are almost the same in performance
