Hello,

I would like to know if AWR1843Boost includes Automatic Gain Control (AGC). If yes, How we can turn it off. I cannot find any information in the user guide or any related documents.

Thank you in advance for your help and response.

Hello,

There is no ACG but all mmwave devices have internal calibrations to maintain consistent gain and performance across temperature. This is handled by the firmware and has nothing to do with the EVM itself.

I recommend to review the below app note to understand the calibration mechanisms.

These can all be enabled/disabled via mmwavelink API control. All of the APIs are described in detail in the interface control document (ICD) as part of the device firmware package (DFP).
