AWR1843: Minimum and maximum power with Rx chirp features

Roland Melad
Intellectual 1185 points
Part Number: AWR1843


I have on aWR 1843 with the DCA1000 board. I have few questions on them:

1- In the datasheet, it is mentioned that the sensitivity is -70 dBm, Is this the minimum required signal entering to the receiver with or without the Rx antenna gain.

2- What is the maximum power that can be entered to the Rx side without making any damage.

3- In the mm wave software, at the post processing results, is there anyway to see the signal feature at the receiver side. Like the impulse response or frequency spectrum and so. I saw that for the Tx side but I couldn't find it for the Rx.

    Hello Roland

    Please find my reply below:

    1- In the datasheet, it is mentioned that the sensitivity is -70 dBm, Is this the minimum required signal entering to the receiver with or without the Rx antenna gain.

    <TI> We only mention noise figure of the receiver in the datasheet, we never quote sensitivity. Because that would depend on your chirp configuration, detection algorithum etc. that you use.

    2- What is the maximum power that can be entered to the Rx side without making any damage.

    <VD> Absolute max signal level is +10dBm

    3- In the mm wave software, at the post processing results, is there anyway to see the signal feature at the receiver side. Like the impulse response or frequency spectrum and so. I saw that for the Tx side but I couldn't find it for the Rx.

    <VD> Are you referring to mmwave SDK or mmwave studio software. Both have receiver data spectrum /FFT done. Tx data cannot be analyzed directly only the data received on the Rx can be analyzed.

    Regards,
    Vivek
