Hi,
With all internal calibration of the awr1243 enabled what would be a reasonable expectation of the RMS phase drift over time of TX-Rx pair signals path within+-10 C of ambient (e.g. 20C ) temperature.
Thank you,
Vladimir Kolinko.

Hello Vladimir,
Within a +-10deg temperature range the phase drift of Tx-Rx pair would be very small . But if you have the run time calibrations enabled and if the temperature crosses a boundary where the gains a changed internally then there could be large phase jump (in absolute terms) at that point. This jump would be seen across all the Tx- Rx pairs of the device , so typically its not an issue. But incase its an issue for your application you can disable the run time calibrations to avoid any phase jump.
