Hi,

For IWR6843, on the datasheet only have power consumption for 1T4R and 2T4R, how about the power consumption for 3T4R?

Thanks.

Hi Andy,

We don't offer 3T on all at once on the device. Is the customer trying to do this?

Nathan,

From datasheet IWRL6843 support 3T, i don't see any limitation for 3T, can u let me know the background?

Hi Andy,

It's not a device limitation, but we don't support it outside the context of TX beamforming. Is that what the customer is attmepting?

Hi Andy,

Based off the datasheet, you could add 0.06 W for 24% duty cycle and 0.12 W for 48% duty cycle as an estimate. We do not have additional info here.

Nate
