Improvement Of Waveform Efficiency Using A Compensation Circuit

In order to improve the efficiency(usable RF to total pulse) of a klystron modulator, a system using a solidstate compensation circuit has been developed. This system remarkably improves a flat-top and flatness of the output waveform of the modulator by means of waveform synthesis. This paper presents the design and specifications of the compensation circuit and the results of a preliminary test using a line-type modulator.
