TECHNICAL ABSTRACT ( Limit 2000 characters, approximately 200 words)
An innovative, ultra low noise, single chip cavity oscillator is proposed. The oscillator is fully integrated on standard MMIC process. It operates in the frequency range of 50 ? 100 GHz with phase noise of -112 at 100 KHz offset. At the core of the oscillator is a rectangular cavity based resonator. To our knowledge, this is the first ever implementation of a waveguide cavity on standard MMIC process. This new technique, will allow the realization of ultra small high performance integrated oscillators for future market demands. In the future, a phase locked oscillator can be implemented on a single chip. The PLO will consist of a cavity oscillator, phase frequency detector, prescaler and a loop filter. All components can be integrated on a standard GaAs HBT process.

POTENTIAL NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Signal sources are critical components in all communications and radar systems. Miniaturized fundamental frequency oscillators will serve the need for receivers in deep-space transponders, radars for monitoring planets and earth atmosphere, radio-frequency spectrometers, radiometers, and others.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Miniaturized MMIC sources will be useful in all microwave transmitters and receivers for all applications. Commercial systems operating MMW frequencies include point-to-point radio links, satellite ground stations, automotive radars, and others. Many of those systems require portable and un-attended terminals in which the size/weight of components become a major limiting factor. The proposed program will lead to partial solution of those problems in all those commercial systems. . The projected number of terminals for those systems add up to millions, representing a large market comparable to cellular and personal communication systems operating in lower frequency bands.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
