Pulsed microwave effects on electronic components

An investigation of short electromagnetic pulse (500 ps~500 ns) effects on some electronic ( microwave ) components, such as low noise amplifier(LNA), limiter, mixer, is summarized in this paper. Not only damage thresholds of some microwave components but also their regularities have been obtained by experiments and theoretic analyses. The relation of the threshold with pulse duration and rise time of the electromagnetic pulse were studied by changing the simulation pulse generatorpsilas output parameters. The features and the principle of microwave effects on microwave components are also discussed in this paper. The test data obtained in our study have been used to improve electro-magnetic compatibility for some microwave devices and systems.
