The Stability

In recent years, nanosecond pulse power techniques used in the millimeter-wave solid-state pulse power amplifiers attracted much attention. The rise- and fall-time of the pulse, the flatness of pulse-top and the stability of pulse-to-pulse, which have play important roles in a nanosecond pulse power generator techniques, and directly determine the system performance. In this paper, a method using the outbreak current with low-voltage to drive MOS-FETs is proposed. The measured results show that the rise- and fall-time of the output pulse is less than 1.5 ns with a pure resistance 0.5Ω, and it only needs two 12V power supply to give a output current of 20A with a pulse width of 160 ns at a repetition rate of 540 kHz in continuous mode. A flatness of 3% for the output voltage was obtained,which meet the requirements of ka-band solid-state millimeter-wave pulse power amplifier.
