The direct conversion of dc energy to rf pulses with high efficiency has many potential applications. They include (1) the use of high power electrical pulses for pulsed power devices and plasma physics experiments; (2) various applications in high resolution radar and time domain metrology; and (3) the generation of megawatt level microwave and millimeter wave pulses. All these experiments require development of an appropriate switch or an array of switches which can switch high power with extremely fast rise time and zero jitter. For sequential waveform generation several methods have been tried.1,2 In Ref. 1, a series of step recovery diodes was used; however, only low voltage switching has been demonstrated. The prospects of extending this technique to a high power switch are poor because the step recovery diodes encounter breakdown problems at high voltage. In Ref. 2, a frozen wave generator was used for sequential waveform generation.
