Abstract
Thales electron devices has many years of experience in the manufacture of traveling wave tube amplifiers (TWTA) for space probes, which must send large quantities of data back to Earth. The application of TWTA have traditionally used the X band, around 8 GHz, with RF power ranging from 20 to 40 watts. However, the upcoming generation of spacecraft will also use the Ka band, around 32 GHz, at relatively high power levels of 60 watts or more. This paper presents the latest results at TWTA level and explores the different possibilities for higher power.
