Thanks all. Nice to know there is some interest here. I made pleas to various folk at Altera to provide a low cost / low friction entry point into direct RF, similar to RFSoC4x2. Everyone I spoke to did a good job of seeming enthusiastic about this, but I guess time will tell. I also suggested Altera consider sending someone to CASPER25 at ASTRON later this year. I did ask a few SoM vendors if there were any Altera options I should consider which are price-competitive with the (admittedly much slower) RFSoC SoM options. I got laughed at.
