Design Considerations for Ultra-Wideband, High-Voltage Baluns

Abstract

We consider how to build a balun for fast-risetime pulses at high voltage. We are concerned about signals with risetimes on the order of 100-200 ps with high peak voltages and peak powers. We propose the simplest method is a coaxial unzipper. We consider (1) the dielectric strength and maximum coaxial radius allowable while still maintaining the risetime, and (2) methods to reduce the coupling to the common mode. Finally, we calculate the peak electric field and characteristic impedance of the coaxial unzipper at various points along its length using a two-dimensional finite element code. The results of this design will be used to build an ultrawideband antenna system.
