AWR1642: What's the value of phase and amplitude offsets(mismatch) between 4RX channel?

Part Number: AWR1642

Hi,

My customer is concern about the value of phase and amplitude offsets(mismatch) between 4RX channel in AWR1642 chip.

Can you provide the test data which can explain this question?

Thanks.

Regards,

Wesley

    Hello Wesley,
    The change in amplitude mismatch across RX channels across temperature (-40 to 125C junction) is within +- 1 dB and phase mismatch is within +-3 deg.
    It is assumed that the fixed mismatch is initially calibrated out at product level, since that would be largely contributed by the PCB routing. Once this is calibrated out only the variation across temperature remains.
