Abstract :
We present the demonstration of the first traveling wave tube circuit fabricated using ultraviolet photolithography. The complete amplifier demonstrated over 60 W output power at 214.5 GHz with 15 GHz bandwidth in the small signal regime at 14 dB gain. A high-gain 233 GHz amplifier is now under development and predicted to reach over 100 W output power. We present several microfabrication advancements that will be utilized to create the new device.
