Summary :

This paper proposes a low distortion technique which reduces transmitter intermodulation. It is shown that one of the third order transmitter intermodulation products generated can be reduced by using a parallel amplifier configuration which includes a 45 divider and a 45 combiner. It is already known that the other third order transmitter intermodulation product can be reduced by using a parallel amplifier configuration using 90 hybrids. Thus, all of the third order transmitter intermodulation can be reduced by combining these configurations. This paper also shows the experimental results obtained with a parallel amplifier using 90 hybrids and one using a 45 divider and combiner in the K-band. The spectra of these amplifiers are compared, and it is found that third order transmitter intermodulation can be reduced by more than 29 dB in the parallel amplifier using the 45 divider and combiner.
