AWR2243: AWR2243P:Maximum number of AWR2243P cascade connection

Part Number: AWR2243

Hi community member,

Theoretically, how many AWR2243P cascades can be connected at maximum?
For example, is it possible AWR2243P 8pcs cascade connection (24 x TX, 32 x RX anttenas)?

Best regards.

    Yes,

    It is possible to cascade 8 sensors.

    Thank you

    Cruijff, 

    There is no explicit limit. 

    The only limit is maintaining digital sync trigger and LO delay match and maintaining the LO minimum/maximum input power at each of the LO RX ports. This puts restrictions on PCB routing/cabling mismatch, return loss and insertion loss and external LO amplification. Please see the AWR2243 datasheet for LO input/output power minimums/maximums.

    Because the AWR2243 LO has limited output power this restricts entirely passive LO interconnect to somewhere between 4 and 8 devices, depending on the specifics of the PCB routing. 

    Thank you,
