Abstract :
Ultra-wide spectrum (UWS) pulser, in which avalanche transistor is used as its switch, can generate high-repetition and -stability short-pulse, but its power is sharply lower than that of SOS and Tesla generators. Marx circuit is used to increase the power of this type of pulser. Different charged-capacitance and class of Marx circuit determines different waveform and peak-power of output pulse. 20-class and 30-class avalanche transistor Marx circuit pulsers are designed, and the charged-capacitance is 100 pF and 470 pF, then 4 types of waveform are get. The highest output peak-voltage is 2.9 kV, the highest repetition can reach 70 kHz, and keep a better pulse stability, jitter is less than 40 ps.
