Transmission character of glass-ceramic Blumlein lines

The transmission character of Blumlein lines constructed by glass-ceramic plate transmission lines with different electrode width is studied. In order to achieve high-voltage fast-pulse output, positive mismatch load and high field strength photoconductive semiconductor switches were used. In the experiments, high voltage pulses with flat top and 9-ns pulse width were obtained, and the pulse amplitude was more than 20 kV. Low bias voltage causes high PCSS resistance so that output efficiency becomes low.
