Response of high power PIN diode limiter to electromagnetic pulse descending edge

The transient response of the high power PIN diode limiter to the step electromagnetic pulse descending edge is calculated by PSpice. Pulse-inversion is observed in the output of the high power PIN diode limiter while the limiter is affected by the step pulse descending edge. The magnitude of the pulse-inversion is equivalent to or in some conditions even larger than spike leakage. Besides the spike leakage, the pulse-inversion may be another potential safety hazard to the high power limiter. The magnitude of the pulse-inversion increases with the augment of the duration and magnitude of the input pulse, and decreases of the input pulse’s fall time and value of the RF impedance inductor.
