The experimental research of the ultrashort pulses generator with an inductive charge storage has been conducted. It is shown that the serial connection of two step recovery diodes can cause an increase in the pulse signal amplitude. The recommendations for the selection of diodes working in pairs, have been made based on the experimental research results. The circuit improvement, which allows operating modes adjustment for the maximum amplitude of the generated ultrashort pulses at a given direct current has been proposed.
