A device which directly compresses electrical pulses using the concepts of soliton propagation along an inhomogeneous nonlinear transmission line is described. Numerical simulations on SPICE indicate that a 5 V input pulse with a FWHM of 66 ps can be compressed to a ≥10 V output pulse with a FWHM ≤5 ps. A compression factor of ≥7 has been experimentally measured on a low frequency scale model compressor.
