Wideband high-power transmission line pulse transformers

Geometric transformers are often used in radar and communications systems to transition between signal driving and radiating elements that terminate in significantly different geometries with unity input/output impedance. This work demonstrates the design and construction process of a geometric transformer with comparison to simulation and prior art. The focus of this work is on the design, optimization, build and test results of a novel geometric transformer capable of transmitting kilovolt 100-picosecond pulses from a parallel plate geometry into a coaxial geometry, modeled after a transverse electromagnetic (TEM) cell. The transformer operates on a wide frequency bandwidth (.5-2 GHz) with minimal reflection or radiative loss (>1.5 dB loss across the frequency range for both in testing). Further, this work touches on a future project that faces similar challenges under different requirements, and describes how these projects compare in design, production, and outcome.
