AWR1642: The Hardware design of mmwave design AWR1642

Hi all

 When i read the document < TI mmWave Radar sensor RF PCB Design, Manufacturing and Validation Guide>, 

I see this words

Does this means if i copy the line width and space of TI DEMO board, then i can get 50 ohm termination？

In other words， i should be use A/B line for the chip but not any 50ohm termination line. 

Then i can get the 50ohm termination at the end of the chip packdge?

Does it is correct?

Thanks
