Dear ADI Support,


We created 100MHz B/W 5G signal and transmit it from DAC.


The direct signal from DAC seems to be good on spectrum analyzer.


However,  a signal via PA is not good. It is not sufficient with ACP.


So, we want to use DPD(Digital Pre Distortion) function on AD9988.


Does AD9988 support a DPD?


Do you have any documentation that describe how to design DPD on AD9988?


Regards,


Tobe
