The IWR6843 (and the other mmWave devices as well) have three LDO outputs: VOUT_14APLL, VOUT_14SYNTH, and VOUT_PA.
The only information I found was related to the VOUT_PA output which I guess needs to be used for the AWR1243P if it's desired to use all three TX antennae simultaneously.
What are these for? Are they useful for debug?
Are the decoupling caps shown on sheet 5 of the IWR6843ISK schematic (0.22uF and 10uF for VOUT_PA and 1uF each for VOUT_14APLL and VOUT_14SYNTH) required for stable device operation? Is this the reason for the LDO output pins, to be able to connect these caps?
