94-GHz TWT for military radar applications

Abstract

For future military radar applications, high frequency, light-weight TWTs become more and more important. To cover this market, Thomson Tubes Electroniques GmbH several years ago started the development of a 94-GHz TWT. The goal of this program was a TWT (double comb delay line structure) in the 94-GHz frequency range with an instantaneous bandwidth greater than 500 MHz (tunable within 1 GHz) and an output peak power greater than 200 W in the center of the band (150 W over the band) for a duty cycle of max. 10%. The basic design and main test results of the 94-GHz TWT are the content of this paper.
