In this paper we present a new technique, which reduces
amplifier intermodulation. It is shown that the third order
intermodulation products generated by an amplifier can be
reduced by adding a new parallel branch which generates an
IMD(3) of the same amplitude and opposite polarity than the
main branch. This paper also shows that third order
intermodulation can be reduced by more than 30 dB in the
parallel amplifier using a Wilkinson type divider and an 180º
