Semenako, J.; Migla, S.; Solovjova, T.; Tihomorskis, N.; Rubuls, K.; Cirjulina, D.; Spolitis, S.; Aboltins, A. A Novel UWB Pulse Expander Using an Integrated Microstrip Splitter, Delay Lines, and a Combiner. Appl. Sci. 2024, 14, 11641. https://doi.org/10.3390/app142411641

Model of the designed pulse expander.
Pulses at the expander’s input (black) and output (green). Simulation results.
Measured input (duration 210 ps) and output pulse waveforms of the pulse expander with 𝑅iso=∞ (pulse duration 455 ps) and 𝑅iso=100Ω (pulse duration 430 ps). The actual delay between the input and output pulses is not shown to enable comprehensible pulse duration comparison.
