Working designs exist for 1 GW, 1 kHz ultra-wideband (UWB) sources (e.g. SNIPER). As these generators are pressed to higher peak powers and repetition rates, insulation, energy loss due to stray capacitance, and system efficiency (including power supplies and modulators) become critical issues. The EnantioMorphic (mirror image) BLumlein (EMBL) is a new type of vector inversion transmission line pulser which is designed to alleviate some of these problems. The design goals for EMBL are : >500 kV, {approximately}1 kHz rep-rate and <100 ps risetime in a 50 ohm geometry. In addition to the pulse forming line (PFL), EMBL also requires a high rep-rate modulator, primary switch, and peaking switch which will be described. Empirical design equations for peaking switch performance are included.
