Posting an answer I received offline.

"You could refer from the IWR6843 datasheet, it’s applicable to AOP device as well.

I have copied and pasted from the datasheet page 29.

The use-case we are interested in is the 3D overhead people tracker which uses regular power ADC mode, has a 110ms frame time, 224 chirps, 60us interchirp time, and 1TX active at a time (1TX, 4RX). The effective duty cycle is approximately 27% and the DSP + Hardware accelerator are active in our use-case. Will the typical average power for our use-case on IWR6843AOP be higher, lower, or similar to the use-case described in Table 8-4 of https://www.ti.com/lit/ds/symlink/iwr6843.pdf?

Hello Rperezti,

It would be very close to 1.1W Power dissipation i.e. first row of the table.

Thanks and regards,
