HF-UHF pulse shaping for testing high-speed circuits

Abstract

The paper discloses a method of construction and the results of examining of the ultra wideband pulse signals shaping device designed for testing integrated circuits. The paper analyses the devices with linear and nonlinear transformations of the amplitude and phase signal spectrum. Phase method for defining the parameters of the pulse signal is proposed. A shaper on a powerful GaAs current switch is experimentally tested over the front duration and maximum frequency, limits of regulation and the error of assignment of pulse levels.
