    Product Number:  AD9375 
    
    		        		        		        
    Software Version: DPD GUI v3.0
    
    		    		    	
			
    I am trying to configure DPD in AD9375. In configuration tab I see that there are 4 DPD models available but some model parameters like i,j,k,lut values which are given to ADRV9029 for different PA's in the link : https://wiki.analog.com/resources/eval/user-guides/adrv9029/dpd_model_optimization is not present for AD9375. Can I get to know about these model parameters? so that I can iterate quickly depending on PA

      You cannot customize the i,j,k values of the DPD models. You need to use the default models(model0 to model3) that are available as part of the AD9375 configuration.
      

      From UG:
      

      Model 2  is recommended as a starting point for most power amplifiers(PAs), especially for gallium arsenide (GaAs) PAs, and gives good wideband performance, as does Model 3. Model 0 and Model 1 may achieve superior narrow-band performance in some cases. The absence of deeper delay terms in Model 0 prevents the DPD from overfitting on narrow-band signals. Model 1 has also been shown to give marginally better performance for some lateral diffused metal-oxide semiconductors (LDMOS) PAs.
