    Thread Summary
    
                The user inquired about configuring the ADF4159 to supply frequency for the two channels of the ADF5901, asking if both channels should transmit simultaneously or alternately with a phase difference. The final answer states that only one ADF5901 output can be used at a time, and the two channels can be switched for MIMO applications. The ADF5902 is suggested as a more integrated option, but it does not support FSK/PSK modulations or parabolic ramps.

    Hi, 
    

    How should I set the ADF4159 to supply the frequency for the two channels of the ADF5901? Should both channels transmit simultaneously, or should the two channels transmit alternately with a phase difference?
    

    Additionally, I noticed there is a more integrated ADF5902. Would you recommend using the ADF5902 instead of the ADF4159 + ADF5901 for a 24 GHz radar with dual-channel?
    

    

    Looking forward to your reply. Thanks a lot!

      Hi Arnold,
      

      Only one output of the ADF5901 can be used at the same time. two transmit channels can be switched in a different time slot for MIMO applications. 
      

      You can think that ADF5902 is a combination of ADF4159 and ADF5901. However, FSK/PSK modulations and parabolic ramps are not available in ADF5902.
      

      Thanks,
      

      Emrecan
