The IWR6843AOP sensor datasheet and EVMs data sheet has different labelling for TX and RX antenna - TX1 & TX2 are swapped, All RX are swapped
60GHz mmWave Sensor EVMs (SWRU546D – OCTOBER 2018 – REVISED DECEMBER 2020) on Page 51
IWR6843AOP Datasheet (SWRS237A – APRIL 2020 – REVISED APRIL 2021) on Page 35
Which one is correct labelling for TX and RX antenna? i.e. TX and RX antenna numbering
Hello Vithy,
The Antenna placement is correct in both figures, just the perspective is different.
In the datasheet (SWRS237A – APRIL 2020 – REVISED APRIL 2021), Pin A1 is in the bottom right, whereas in the EVM user guide (SWRU546D – OCTOBER 2018 – REVISED DECEMBER 2020), it is the bottom left as pointed by the dot highlighted below :
Hope this makes sense and brings more clarity.

Ishita
