Abstract

A spatially dispersive nonlinear transmission line (NLTL) using axially biased ferrite as the nonlinear medium has been developed. The NLTL is frequency tunable from 0.95 to 1.45 GHz with adjustment of the axial biasing field. A circuit model describing the dispersion of the line has been developed and compared with experimental measurements and time and frequency domain simulations. Instantaneous peak power levels exceeding 100 MW and average power levels of 10s of MW with durations from 4 to 17 ns have been observed.
