AFE7952: RF differences between AFE7950 and AFE7952.

I’m looking at the AFE7952 as a possible chip for a radar design, however I need an RF operating range to go down to around 100MHz.  Initially it looked like the AFE7952 could do lower than 600MHz (in the chip selection it indicates 0-12GHz), but after getting the datasheets it looks like it is only 600MHz-12GHz range, which is the same as the AFE7950.  Could you tell me if there is any difference in the RF performance between the AFE7952 and the AFE7950?  I know the AFE7952 does have differences in the data transfer, with floating point vs fixed.
