High power Ka-band transmitter for planetary radar and spacecraft uplinkA proposed conceptual design of a 400 kW CW Ka-Band transmitter and associated microwave components to be used for planetary radar and serve as a prototype for feature spacecraft uplinks is discussed. System requirements for such a transmitter are presented. Performance of the proposed high power millimeter wave tube, the gyroklystron, is discussed. Parameters of the proposed power amplifier, beam supply, and monitor and control devices are also presented, Microwave transmission line components consisting of signal monitoring devices, signal filtering devices, and an overmoded corrugated feed are discussed. Finally, an assessment of the state of the art technology to meet the system requirements is given and possible areas of difficulty are summarized.
