I haven't done a detailed comparison of the specs (I believe that they are similar).  The one advantage of the ADF4350 is that there is already UHD support for it since this part is on the WBX and SBX Ettus daughtercards.

Ok. Anyway, it will be much faster then request of samples from Moscow.
Sorry regarding ADF4350 parameters, I mixed up it with ADF4360.
What do you think about ADF4350 and HMC830 differences and usability?

Andrey.
