AWR1642BOOST-ODS: TIDA-020011 - Different board stackup

Part Number: AWR1642BOOST-ODS
Other Parts Discussed in Thread: TIDA-020011

The PCB stackup for awr1642boost-ODS and TIDA-020011 seems to be different,

Can you please advise, if I use the TIDA-020011 design as it is on the PCB stack up meant for awr1642boost-ods (due to the silver immersion finish) will I need to modify the antenna elements for impedance matching?

In other words, are the antenna element dimensions and GCPW transmission line of TIDA-020011 and awr1642boost-ODS, are they exact copies or have they been adjusted for different PCB stack up.

    Krishna, 

    You should be able to use the same stackup from the boost-ODS board with the layout from TIDA-020011. The same transmission line/layout was used for both designs. 

    More general information on layout and stackup guidelines can be found at

    I already have this document, but the ODS userguide document doesn't explicitly state the stackup used like you have done in your TIDA0211 design document, the design files for ODS are given in Altium and I have no access to Altium to cross verify. I assumed the ODS board stackup is the same as in the document you have referred to. Many thanks for your help
