Abstract
Summary form only given, as follows. Considerable interest exists in developing high power microwave amplifiers at W-band for both commercial industrial and military applications. A multi-purpose harmonic gyrotron traveling wave tube (gyro-TWT) amplifier that can stably deliver moderately high peak and high average power in W-band has been designed and will be presented. The designed 400 kW peak and 400 W average power harmonic gyro-TWT amplifier will be powered by a 2.5 MW electron beam emitted from a magnetron injection gun (MIG). The TE/sub 02/ overmoded interaction waveguide will be sufficiently large to handle the RF power generated and provide appropriate clearance for the high current electron beam. Operating in the second harmonic of the electron cyclotron frequency, high RF output power can be generated. An innovative mode selective interaction circuit will further prevent the amplifier from oscillating in undesired modes. Also included in the design to be presented are details of the MIG and RF input coupler.
