We report the first measurements of picosecond pulse propagation on transmission lines patterned from YBa/sub 2/Cu/sub 3/O/sub 7//sub -//sub x/ films. Distortion-free propagation of high current density transients is demonstrated. The high-frequency properties were analyzed by careful study of the relative phase delays of the electrical transients as the temperature of the sample was varied from 1.8 K to T/sub c/. Simulations using Mattis--Bardeen complex conductivities showed good agreement with the measured results. High-frequency critical current densities in excess of 10/sup 5/ A/cm/sup 2/ were measured.
