2020年10月29日 · The pulse generator based on drift step recovery diode (DSRD) has broad development prospects in the research of high pulse repetition frequency (PRF), high power pulse generators. In this letter, a pulse generator based on DSRD is successfully developed.

Drift-step-recovery diodes (DSRDs) are used as ∼1 ns high-voltage opening switches by pumping them slowly in the forward direction and then pulsing them quickly in the reverse direction. The fast opening occurs when the reverse current discharges the carriers that were stored in the DSRD junction during the forward cycle.

In this paper, a cascaded configuration of two DSRD-based high-power short-pulse generators with gas discharge switches was used. The high-power pulses generated in the first stage feed the second stage in order to generate shorter pulses with higher peak powers. A prototype was implemented based on this idea.
