Abstract

This article introduces the design and experimental study of a Ku-band continuous wave tunable klystron. The device mentioned above adopts a single electron beam and six tunable resonant cavities, it operates at a cathode voltage of 9.5 kV, and the cathode emission current is 1.05 A with an axial guiding magnetic field of 0.34 T. To reduce the heat dissipation of the collector and improve the efficiency, the device adopts a four-stage depressed collector design, and the collector adopts forced air cooling for heat dissipation. Finally, the assembled sample tube is tested in detail. The dc beam transmission is over 99% and the high-frequency beam transmission rate is above 97%. The device can output continuous wave power of over 2.6 kW in 1.2-GHz tuning frequency range, with 1-dB instantaneous bandwidth (BW) exceeding 60 MHz at each working frequency channel. Tube gain exceeds 51 dB, and efficiency exceeds 40%. The experimental results are in good agreement with those obtained by the 1-D and 3-D simulation. The development of this device provides important technical reference for wideband mechanically tuned klystron products and has significant importance.

期刊介绍： IEEE Transactions on Electron Devices publishes original and significant contributions relating to the theory, modeling, design, performance and reliability of electron and ion integrated circuit devices and interconnects, involving insulators, metals, organic materials, micro-plasmas, semiconductors, quantum-effect structures, vacuum devices, and emerging materials with applications in bioelectronics, biomedical electronics, computation, communications, displays, microelectromechanics, imaging, micro-actuators, nanoelectronics, optoelectronics, photovoltaics, power ICs and micro-sensors. Tutorial and review papers on these subjects are also published and occasional special issues appear to present a collection of papers which treat particular areas in more depth and breadth.
