A Generator of High-Power Nanosecond Pulses of Quasi-Rectangular Shape

A generator of powerful nanosecond pulses that contains a storage capacitor, a segment of a coaxial cable, and closing and opening semiconductor switches has been developed. With a storage-capacitor charging voltage of 12 kV, the generator allows switching quasi-rectangular voltage pulses with an amplitude of similar to 26 kV, a rise time of similar to 4 ns, and a fall time of similar to 6 ns into a 75 Omega load. The half-maximum pulse duration is similar to 45 ns, and the "jitter" relative to an external triggering signal is less than 2 ns. The possibility of increasing the generator output power and the duration of output-voltage pulses is shown.
