Description

Technical field [0001] The present invention belongs to the field of semiconductor switching and pulse power source, relates to a heavy frequency nanosecond pulse generation circuit based on a drift step recovery diode. Background [0002] High repetition rate pulse power device is an important development direction of pulse power technology, which is widely used in high power microwave, high power laser, ultra-wideband radar and other fields. For most pulsed power devices, the parameter characteristics of switching devices limit their peak power, operating repetition rate and service life. In addition, the stability and reliability of the pulse waveform output of the device is also often dependent on the performance of the switch. [0003] Traditional power switches are mostly gas devices, such as: high pressure gas spark switches, hydrogen gate flow pipes, vacuum trigger switches, etc., characterized by large power, mature design principle, wide application, but by the nature o...
