Abstract
Abstract A technique for generating high-voltage, wide dynamic range, shaped electrical pulses in the nanosecond range. Two transmission lines are coupled together by resistive elements distributed along the length of the lines. The conductance of each coupling resistive element as a function of its position along the line is selected to produce the desired pulse shape in the output line when an easily produced pulse, such as a step function pulse, is applied to the input line.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
In a technique for generating a highly reproducible, high voltage, dynamic range electrical pulse having an increasing pulse amplitude as a function of time by a completely passive system, the apparatus comprising a ground plane, a pair of conductors of selected length separated from said ground plane by a suitable dielectric, and a plurality of entirely passive, entirely resistive elements positioned along said length each of which couples said pair of conductors, the conductance of each of said passive resistive elements increasing with position along said length whereby the application of a step function pulse to one of said conductors produces said pulse having an increasing pulse amplitude with time as an output at the other of said conductors.
Claim 2
Dependent Claim
119 words
