Effect on the linearity improvement of TWTA by combining RF predistortion linearizer and digital predistortion algorithm

In order to keep the adaptive digital predistortion algorithms valid,usually the output power level of the TWTA must be reduced,which corresponded a reduced efficiency of the TWTA.A predistortion technique was proposed by combining RF predistortion linearizer with adaptive digital predistortion algo...
