AWR1843BOOST: Thickness of top layer of RF PCB

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

HI,

I am referring the "TI mmWave Radar sensor RF PCB Design, Manufacturing and Validation Guide" document for the RF PCB design. In this document it is mention that the thickness of top layer should be 0.5 oz. Please refer the below image.

But when I reviewed the stack up of AWR1843BOOST, I notice that the top layer thickness given is 1 oz, Refer the below image.

So please clarify this and tell me what is the thickness of top layer we should consider during the design of PF PCB for AWR1843.

Please find the document attached.

Thanks & Regards,
