Building a High-Current, High-Frequency Pulse Generator

Click For Summary
SUMMARY

The discussion centers on constructing a high-current, high-frequency pulse generator capable of producing peak currents between 100A and 1000A, with pulse durations of approximately 0.5 nanoseconds and a frequency of operation around 1 GHz. Participants suggest using a robust step-down transformer, potentially home-built, to achieve the necessary specifications. The emphasis is on the design challenges and solutions for generating such high-frequency pulses efficiently.

PREREQUISITES
  • Understanding of high-frequency circuit design
  • Knowledge of transformer construction techniques
  • Familiarity with pulse generation methods
  • Experience with high-current electronics
NEXT STEPS
  • Research high-frequency pulse generator design techniques
  • Explore step-down transformer design for high-current applications
  • Study the effects of inductance and capacitance on pulse shaping
  • Investigate safety measures for handling high-current circuits
USEFUL FOR

Electrical engineers, hobbyists in high-frequency electronics, and anyone involved in designing pulse generators for high-current applications.

Hi,

I need some help/ideas/direction... I need to build a pulse generator that is capable of generating a peak current between 100A~1000A that lasts for about 0.5ns and can be ready to pulse again in 0.5ns so the frequency of operation is around 1Ghz

Help!

Thanks

How about a really stout step-down transformer(likely home-built).
 

Thread 'uA709 op amp compensation'

Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
