It is. And there's other versions out there. What I was originally thinking about was how one could leverage off what's available today (i.e. the SDR1000), but the Phoenix approach is equally valid. I'd use discrete interconnects rather than a backplane, but that's personal preference. There's also the question of whether the data conversion should be integrated with the RF module. There's good and bad for both approaches, but philosophically, I like considering the RF module being a RF on one end and (high speed serial) digital data stream on the other.
