HARMONIC DISTORTION SUPPRESSION TECHNIQUE FOR SHORT-WAVE POWER AMPLIFIERS
The technique to reduce the harmonic distortions level in the output signal spectrum of short-wave high frequency power amplifier is proposed. This technique is based on introducing in high frequency path additional injection channels allowing to mitigate the harmonic distortions across the whole frequency output range. The signal generation approach for additional channels and architecture for it’s implementation are suggested. It’s given the experiment results of employing the technique studied to reduce the harmonic distortions level in the short-wave high frequency power amplifier.
