Abstract
A channelized amplification system and method for mitigating non-linear amplification effects and controlling spectral re-growth is disclosed. A system includes an input frequency divider for converting a first signal into a plurality of frequency band signals and a plurality of channelized high-efficiency non-linear power amplifiers coupled to the frequency divider. Each of the plurality of frequency band signals occupies a frequency band that is different from one another. The plurality of channelized high-efficiency non-linear power amplifiers receive and amplify the plurality of frequency band signals and produce a plurality of non-linearly amplified signals. The system further includes a frequency combiner coupled to the plurality of channelized high-efficiency non-linear power amplifiers. The frequency combiner combines the plurality of amplified signals and produce a second signal. The system further includes an output band-pass filter coupled to the frequency combiner. Each of the frequency divider and frequency combiner can be a duplexer or a diplexer when the number of the plurality of frequency band signals is two. The system further includes an input band-pass filter for spectrally shaping a signal and a distributor for distributing a signal to a plurality of amplification modules. Each of the amplification modules includes a corresponding frequency divider, a corresponding plurality of channelized high-efficiency non-linear power amplifiers, a corresponding frequency combiner and a corresponding output band-pass filter. The system further includes a radio frequency up-converter coupled to the input band-pass filter.
