Development of a 10-kilowatt 1700-2400 megacycle CW klystron amplifier

The paper describes the design of a high power klystron amplifier which has several unusual features. These are unusually wide tuning range capabilities, exceptionally high beam efficiency, unique modulating capabilities for single-side band, high level modulation, and considerable flexibility in simultaneous bandwidth adjustment. The paper deals with the design aspects of the tube, some unusual fabrication techniques used in construction, discussions of a high efficiency cathode under continuous high voltage conditions, and test data under several conditions of operation. In addition there is some discussion of engineering problems associated with the application of this tube to a practical forward scatter communications system.
