IWR1642: RX Gain and Phase Compensation in MIMO mode

Part Number: IWR1642

Hi,

We know that we need to do RX Gain and Phase Compensation. In MIMO mode, there are virtual RX channels compared with non-MIMO mode. Is there any difference on RX Gain and Phase Compensation in MIMO mode? If yes,would you pls kindly advise?

    Hello Chris,
    Internally there is no difference in our gain and phase settings in MIMO and non MIMO modes. In case there is any phase/gain mismatch on the system (could be due to board traces and routing also) , this needs to be calibrated out separately by the customer and accounted for in their algorithms.
