Hi,

I want to know IWR1443 output is temperature compensated or not. What is change in distance output of IWR1443 with temperature?

Thanks,

Akshay

Hi Akshay,

IWR1443 device is temperature compensated. Is there a specific problem you are facing due to temperature?

Please find the below application note on "Self-Calibration in TI’s mmWave Radar Devices"

Thanks and regards,

Hi Chethan,

Thanks for document. I found ~4 mm deviation in IWR1443 output (High accuracy FW) on increasing temperature to 70 deg C.

Thanks,

Akshay

Hi Akshay,

Are you using ES2.0 or ES3.0 Silicon?

Would you be able to support some data or plots to support your experiment?

Cheers,

Akash

Hi Akash,

I am using ES2.0. I have recorded below graph on changing temperature to 70 C.
