AD 9361 with DPD for LTE

In order to use DPD (digital pre-distortion), we need to have in the TX chain a bandwidth 5 times the bandwidth of the usefull signal.


Considering LTE BW  = 5 MHz, we need at least a BW = 25 MHz for the TX chain, but only 5 MHz in the RX chain.


Is it possible to set AD 9361 to work in these conditions? (BW TX = 25 MHz, BW RX = 5 MHz) ?


In this case, what will be the sampling rate needed? 


Will the sampling rate be the same for RX and TX or is it possible to set it independently for ADC and DAC?
