| Abstract: | This paper discusses in detail the failure mechanisms involved in putout burning-out and SWR increase observed from the booster of TWT amplifier chain B -284 and presents the corrective actions used in control the mechanisms. The result obtained from performing the corrective actions in practice is also reported in this paper. It is shown that the corrective actions used in control of the failure mechanisms are feasible and effective. |
