Satellite communications systems have recently provided an application for high-power CW travelling-wave tubes. In this paper we describe the transmitter power amplifier tubes now operating in the American and French ground stations which are in communication via American Telephone and Telegraph Company’s Telstar satellite. The tube has been designed for a reasonably broad bandwidth of ~13% centered at 6100 Mc/s. The output power is in excess of 2000 watts and the high-level gain is better than 27 dB over this band.
