The MAX2010 is an open loop predistorter the IMD improvement you get depends on how well the expansion curves match the compression curves of your amplifier. From what I remember it would match a class B amplifier reasonably well, but could not cope with a Doherty amplifier. I've only tried to use this IC once and after a lot of fiddling managed about 6dB improvement but it did not stay stable over temperature, which could be corected, or the bandwidth of the amplifier, which could not.
From your other thread, the SC1894 was much better, but only for wideband signals, it's not much good for multicarrier amplifiers with narrowband TDMA signals.
