Compared with the monopolar pulser, the bipolar pulser is more suitable to be the excitation pulser of the ultra-wideband radiation system for its less content in low frequency range. In this paper, a high-power bipolar sub-nanosecond pulser based on the avalanche transistor is developed through the power synthesis method, whose principle is combining two monopolar pulses with different polarity together. Experimental results show the designed bipolar pulser has a 1.8-kV peak-to-peak amplitude, 94-ps rise time and 400-kHz maximum PRF.
