Abstract :
This paper proposes a new predistortion linearizer module for TWTA enabling to use broadband multi-carrier signals for new Telecom satellite transmit sections. A state-of-the-art NPR performance was obtained over the entire 10.7-12.75GHz Ku-band for multi-carrier signals up to, at least, 1GHz instantaneous bandwidth.
