The amplifier will be use with 16-QAM modulation (require high performance -IMD)
transistors BLF542 or BLF404 ???
Do you have vfone some measurements data IMD ???
In this case use BLF542 which allows you to back-off the output power, to avoid the high peaks of the modulation.
IMD3 at maximum output power (5W) is approximately -30dBc, and better than this at 3W.
