Abstract
This invention relates to the Linearization of multitone or multiple signal amplifiers or like devices. The telecommunications industry is currently employing amplifiers, transmitters or other active devices that are not only amplifying complex digital and analog modulation formats, but are transmitting or amplifying multiple complex signals simultaneously. In order to meet the transmission requirements, amplifiers or transmitters must exhibit extreme phase and amplitude linearity. Deviations from linearity are distortions which lead to intermodulation of the signal components; those intermodulation products appear variously through out the spectrum and cause interference between signals, which in turn degrades the amplified signals. Today the amplification of these signals requires the use of feedforward technology to achieve the performance required to meet government spectrum modulation mask requirements. This invention provides an important advance in the art of extreme phase and amplitude linearity.
