Experimental demonstration of nonlinear lumped element transmission lines using COTS components

Abstract

In recent years, there has been great interest in using nonlinear lumped element transmission lines (NLETLs) to generate RF pulses. The NLETL consists of an LC-ladder network where either the capacitive element or the inductive element is nonlinear. There has been the suggestion of using a hybrid line where both the elements are nonlinear. This paper focuses on the implementation of a low-voltage nonlinear capacitive line (with nonlinear capacitors but linear inductors) using commercial off-the-shelf (COTS) components. Experimental results that show good match to the simulation results obtained from the circuit model of the NLETL will be presented.
