Generation of 1 Megawatt RF Peak Power in S-Band Using Klystron

Abstract

The microwave tubes are electron guns for generating linear beam tubes. There are different kinds of tubes like conventional tubes, microwave tubes and so on. But, the drawbacks of conventional tubes are that they are limited to frequencies below 1GHz while the microwave tubes can be used for higher frequencies as well. There are different microwave tubes like Klystron, magnetron and travelling wave tube. Hence, we make use of S-band cavity Klystron as it is simple to design as compared to other tubes power. The Klystron tube which takes AC input and gives RF output is widely used as communication equipment and radar system. The high-frequency applications above 1 GHz, the inter-electrode capacitances and transit-time delays of standard electron tube structure become exorbitant. However, there are so many creative ways in which tubes may be fabricated, and several high-frequency electron tube designs have been made to overcome these encounters. Klystron microwave tube is used as an amplifier for the generation of 1MW RF peak power because of its simple design and linear beam tube. The advantage of using Klystron tube is it can be operated at higher frequencies and there is no mutual coupling between the cavities of the tube.
