Abstract :
A major concern relating to the transmission of Internet services by means of satellite has been the linearity of available high power amplifiers (HPAs). Traveling wave tube amplifiers (TWTAs) offer the greatest efficiency and power capacity, but are somewhat limited in linearity. This paper investigates the use of linearized TWTAs for the transmission of high date rate bandwidth efficient traffic.
