2005 Phase II
High Reliability Oscillators for Terahertz Systems
Virginia Diodes, Inc.
Charlottesville, VA
INNOVATION
- Developed frequency multipliers and multiplier chains with improved performance and reliability for NASA missions.
Complete Oscillator System with Enhanced Frequency Multiplier
- Designed, developed and demonstrated a series of varactor multiplier circuits that are suitable for use in local oscillator chains for space based radio astronomy and Earth remote sensing programs.
- Developed several methods to investigate the complex interactions between cascaded frequency multipliers.
- Demonstrated a new directional coupler technology, useful for testing components and systems, as well as, in the implementation of frequency extenders for vector network analyzers.
- $2.3 million in sales attributable to the work done under this contract.
- Customers in government agencies, university, industry, in the US and abroad.
- New designs in use on a few commercial satellite projects and as prototypes for future missions.
- Local oscillator sources are important for radio astronomy, Earth and atmospheric studies, and planetary exploration.
- Companies technology is undergoing qualification for application in the Core Global Precipitation Measurement (GPM) spacecraft microwave imager and the Joint Polar Satellite System (JPSS) Advanced Technology Microwave Sounder (ATMS) instruments.
- Technology is under study for an instrument for an ice cloud studies mission.
