This paper describes an automatic test equipment for integrated circuits. Most traditional automatic test equipments focus on integrated circuits tests in conventional environments. They usually can not test integrated circuits in the extreme environments, such as thermal cycling, thermal vacuum, vibration and shock. Some can accomplish the tests in only(More)
—If sampling frequency is not high enough, the effect of adaptive memory polynomial predistortion linearizer is not very good for TWTA linearization. In order to keep the adaptive memory polynomial predistortion linearizer valid, usually the output power level of the TWTA must be reduced, which corresponds to a reduced efficiency of the TWTA. In this paper,(More)
