IWR6843: So we can only transmit -10dBm in the U.S.?

DARIN

Part Number: IWR6843

From this related thread, the FCC requirement is -10dBm peak conducted AND +10dBm peak EIRP. Your suggestion is to back off power. If we back power off 20dB, the IWR6843ISK is practically unusable in a people-counting scenario. It is a peak measurement and not averaged, so we can't take advantage of the sweep. What am I missing? The configuration for all of the TI demos have 0dB backoff, which is what we have been working with. Please help me understand how anybody can work in this band with FCC. Thanks.

Hi,

Even in the use case you referenced that will be a 13dBm EIRP power backoff. Does your application require more power than the FCC limit? Can you provide more details on the application?

BR,

Hi,

I assume you were able to resolve this and will be closing the thread. Please reply if you still need assistance or make a new post referencing this one.

We were able to modify some of the other settings on the receive side to make this work. Thank you.
