A study of reliability for twelve-hundred watt pulse amplifier modules used in wind profiler high power transmitters.

摘要

This comprehensive reliability study of a high power amplifier discusses the essential elements needed to make a reliability prediction. The major emphasis of this study is to complete the reliability prediction using a parts stress analysis method. This study includes important elements of thermal analysis, finite elements analysis, direct comparisons with field data, criticality analysis, and failure modes and effects analysis. Results demonstrate that reliability predictions using parts stress analysis, and then refining the predictions using criticality analysis, can be an important aid to forecasting the future performance of hardware.
