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 29dB in the parallel amplifier using the 45°divider and combiner.
