ABSTRACT:
A composite amplifier includes a main power amplifier (10) and an auxiliary power amplifier (12), which are connected to a load (14) over a Doherty output network (16). A non-linear function (18) and a cross-coupling filter (22) emulate the non-linear behavior of the output current of the auxiliary power amplifier (12) and the resulting emulating signal is subtracted from the input signal to said main amplifier (10).
