How can I model the AD9361 gain stages

How can I model the AD9361 gain stages to perform a cascade analysis and to help optimize the gain settings of the individual stages (LNAm mixer, TIA, LPF to optimize IP3 performance and minimize saturation of the individual stages? For instance I would like to model the individual gain stages of the AD9361 in ADISimRF (similar to how ADI models the ADRF6518 with several stages) in order to perform a cascade analysis. Is there a model that I can use for ADISim RF?

 

Also page 35 of UG-570 specifies the recommended input voltage to avoid compression, In a similar fashion can you please indicate the recommended input power or voltage ranges to avoid compression for the different gain stages?
