A linearizer for satellite communications
Abstract
A nonlinearity compensating method for a microwave amplifier and the configuration of a wide band linearizer with amplitude and phase equalizers are described. A substantial reduction of intermodulation products has been achieved in helix and coupled cavity type TWT power amplifiers using the linearizer. The linearizer can also be used to reduce the side band in AM, SSB-AM and PCM communication systems.
