Title: An all MMIC Replacement for Gunn Diode Oscillators
Agency: NASA
Contract: NNG05CA08C
Award Amount: $600,000.00


The objective of this Phase II project is to develop and demonstrate a compact and reliable oscillator technology for the frequency band from 100 ? 250 GHz for use in terahertz local oscillators and transmitters. The new oscillators rely on MMIC technology that is reliable and robust, offers the best overall performance and will be suitable for volume production and commercialization. These oscillators meet immediate needs for NASA's Earth Science program, specifically for terahertz radiometers for studies of the atmosphere and climate change. The oscillators are also useful for a wide range of other scientific, military and emerging commercial applications. The Phase I study demonstrated the feasibility of the new oscillators through the development and demonstration of an oscillator at 146 GHz suitable as a driver for an 874 GHz cloud ice radiometer being developed at NASA/GSFC. This new component greatly exceeds the performance of any other commercially available oscillator technology while maintaining a compact size, power efficiency and all solid-state construction. The Phase II research is focused on achieving greater power for higher frequency terahertz sources, improving power efficiency, achieving more compact integration of the subcomponents and extending the basic design concept throughout the 100 ? 250 GHz band.
