The doping density is extremely small near junction area, due to which the charge storage is negligible near the junction and this leads to fast switching of the diode from ON state to OFF state.

SURFACE MOUNT STEP RECOVERY DIODE ASRD 800 SERIES DESCRIPTION: The ASRD 800 Series of Step Recovery Diodes are Designed for Synthesiser and Sampler Applications Requiring a High Performance to Cost Ratio. They depend on extremely fast recovery time, often referred to as âsnap timeâ to generate pulses rich in harmon-ics. We ﬁrst explain the operation principle However such devices can not generate nanosecond pulses up to some hundreds volts on the antenna terminal. 0000015670 00000 n Step Recovery diode is a semiconductor device with unusual doping. Using custom epitaxial wafers, our process ensures high reproducibility. Step Recovery Diodes have relatively little capacitance change under reverse bias and are used for higher efficiency applications.
