I don't see differences in datasheets between the discontinued 907LP5E and the new 907ALP5E.
The foundry that Hittite was using for the 907 shut down, and we had to redesign on a different foundry
that had slightly different characteristics. The intent was to make the new silicon a drop in replacement
which in this case, we succeeded.
I'd like to add that the HMC907ALP5E is currently under development and is thus still "Pre-release".
