Abstract

Using avalanche transistor as the switch of Marx circuit, a new type of all-solid-state pulse generator is researched, which can generate short unipolar pulse. The peak-voltage is 2kV as the load resistor is 50Ω, the pulse width is 1.6ns, the rise time is 250ps, the jitter is less than 30ps, and the repetition can reach to 30kHz. Then, combining short pulse through mcirostrip power combiner is analyzed. Four high-stability pulse generators are combined, which generates higher peak-voltage to 3.9kV. The combining efficiency reaches to 97.5%.
