Silicon Step Recovery Diodes
Features
Output Combs to 40+ GHz Transition Times down to 35 ps Screening per MIL-PRF-19500 and MIL-PRF-
38534 available
Description
The diodes feature fully passivated, true mesa construction for sharp transitions and improved stability. The beam lead SRDs have the industry’s fastest transition times for millimeter wave multiplication and picoseconds pulse forming.
