Solid State Ultra-Wideband Microwave Source

The purpose of this project is to design a low cost pulser that can produce a 100kV pulse with a continuous repetition rate of 2kHz. The objective device will have the size, mass and reliability to be compatible with use in aircraft. In contrast, current pulsers tend to be bulky, expensive, have limited lifetimes, and require substantial cooling systems. Time Domain Corporation (TDC) intends to use Drift Step Recovery Diodes and Transistors, a novel semiconductor technology, to produce the required pulses. TDC will also investigate coherent addition of pulses and the use of Silicon Carbide for key components. Experience to date indicates the objective is feasible and can be accomplished by making a single large device or by coherently summing the outputs of smaller devices.
