Hi Experts,

I have AWR1843 BOOST RevA. I want to enable the Tx beamforming by enabling all the 3 Tx simulatenously with lab0007_medium_range_radar (Automotive toolbox). For this, 0 ohm registor needs to be mounted. Is the following place in red circle correct?

Best regards,

Ken

    Hello Ken,

    Your understanding is right and you need to mount a 0 ohm resistor on the highlighted circle.

    3 Tx Simultaneous operation is supported in AWR1843 with 1V LDO bypass and PA LDO disable mode. In this mode 1V supply needs to be fed on the VOUT PA pin. This is the reason for the modifcation.
