Hello,
In the IWR6843ISK schematic, the RF voltage is 1.0V. I looked through multiple labs (vital signs lab for example), I don't see ldoBypassEnable being called anywhere.
1) Isn't LDO enabled by default, hence 1.3V has to be provided?
2) Am I searching for the wrong thing (I searched ldoBypassEnable and only found it in the header file)?
Thanks,
Faiz
Faiz,
Please refer below E2E thread if you ware looking for LDO bypass feature ennoblement.

In the ISK and ODS boards we are providing 1V directly to LDO input and It's output also shorted to Vout_PA as shown below.
Even if LDO is not bypassed, this path will provide the necessary voltage and current through external path to the device.
Thanks and regards,
