Subnanosecond pulse generator operating with arbitrary load

A subnanosecond pulse generator based on two Blumlein pulse-forming lines (PFL) is investigated. The width of an output pulse of the generator does not depend on its load resistance in contrast to the basic structure of a Blumlein PFL. Therefore, the generator does not need to be matched to load in order to avoid the reflections. The circuit design was simulated by PSPICE simulation software. The reported subnanosecond pulser was made using a microstrip technique. A comparison between measured and simulated results shows good agreement.
