A converter of ultra wide spectrum bipolar pulse with a parallel connected short circuit transmission line is designed. Its operating principle and the analysis of wave propagation are described in this paper. The experiment results indicate that the peak-peak voltage of output bipolar pulses almost access the peak voltage of the input pulse with pulse width of 6 ns and 2 ns. It is shown that ratio of relative position and amplitude of bipolar pulse can be regulated by changing the length of line and the characteristic impedance. The stability of bipolar pulse depends on the stability of single polar pulse.
