I found that UBX has a bit less of spurs. I assume it is because the whole daughterboard is covered by heatsink panel that plays a role of EMI shield while SBX is open.

I have two USRP X310s and wonder which board between SBX and UBX would be the suitable for me. I'm gonna buy four daughterboards to use it as 2x2 MIMO. One USRP X310 for Tx, the other USRP for Rx. My target frequency is from 1.8GHz to 2.8GHz. According to datasheet, Both UBX and SBX work on the target frequency. I saw the schematic of both SBX and UBX and figured it out that UBX has a significantly different structure from SBX. I wonder, which board performs better "in the target frequency" in terms of MIMO performance(i.e. phase align accuracy, noise level, etc..). I don't have price issue. If the UBX performs better or same as the SBX in target frequency(1.8GHz~2.8GHz), I would like to buy UBX since it has more wide frequency range. Regards,
