Investigation on the EMP damage characteristics of RF/microwave PIN diode limiter

The effects of EMP of different types and different energy will lead to different levels of damage in limiters employed in RF and microwave receivers. After damaged, the limiters still preserve some original functions and thus the systems they served will suffer performance degradation instead of invalidation. In this paper we made research on the damage threshold and damage effects of typical limiters, and discovered that the limiter will suffer irreversible cumulated damage.
