Abstract :
A program was undertaken to develop a high power TWT and associated console to be used as a ground station transmitter for satellite communications. The major objectives of this program were broad bandwidth, high efficiency and long life. The result is a 2.5 kW, CW TWT operating between 7.7 GHz and 8.4 GHz; the efficiency is in excess of 35 percent, and the expected life is over 1,000 hours.
