IWR1642BOOST: PCB Material

Part Number: IWR1642BOOST

I notice that the BOOST and other Ti designs recommend RO4835LowPro, can RO4350B be used instead, if we are simply replicating a TI design for PCB evaluation purpose.

Many thanks I should have searched the forum with the keyword RO4350B instead of wasting your time.

Hello,

It could be doable, for the best performance our recommendation is to do a EM simulation on Antenna and RF transitions to ensure there is very little performance degradation from the original design.

You may refer to below "TI mmWave Radar sensor RF PCB Design, Manufacturing and Validation Guide" for the details about material property care about and transition design details.
