Abstract
The amplitude and width of the ultrashort pulses depend on the performance of the generator’s electronic elements. The usage of step recovery diodes (SRDs) with picosecond switching time can lead to a significant increase in device cost. In this letter, nonlinear transmission line (NLTL) was built and tested using commercial-off-the-shelf components to improve the performance of the generator that is based on inexpensive diodes. The method to control output pulse duration by keeping the constant amplitude was proposed. Measurement results show that generated ultrashort pulse can be compressed using NLTLs and the output amplitude of the compressed pulse is 54 V and the duration is 240 ps.
