Part Number: IWR6843

Hello everybody:        

        what is the minimum receiving level of IWR6843?  which is a concept  as  receiving sensitivity.

tks.

    In radar typically we do not refer to sensitivity levels of a receiver, but just the SNR required for object detection . Based on the threshold set in the detection algorithm the sensor would be more sensitive or less sensitive. 

    Basically from the mmwave IC point of view the receiver noise figure and TX output power are key performance parameters that decide the max range (assuming we are SNR limited and not IF frequency limited). The exact SNR required to detect the object would depend on the object detection algorithm used during processing , so it would vary from user to user and hence there is no sensitivity number for such devices.

    You could use the mmWave sensing estimator to perform link budget analysis.
