Un nuevo método para la reducción de la distorsión de intermodulación de tercer orden

Abstract

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 Hybrid combiner
