To make the terahertz region of the electromagnetic spectrum as useful for scientific, military and commercial applications as the microwave and infrared bands are today.
VDI manufactures state-of-the-art test and measurement equipment for mm-wave and THz applications. These products include Vector Network Analyzer, Spectrum Analyzer and Signal Generator Extension Modules that extend the capability of high performance microwave measurement tools to higher frequencies. VDI's component products include detectors, mixers, frequency multipliers and custom systems for reliable operation at frequencies between 50 GHz and 2 THz. All VDI components include in-house fabricated GaAs Schottky diodes and microelectronic filter structures.
VDI was founded in 1996 by Dr. Thomas W. Crowe, VDI CEO & President. From 1996 to 2001 VDI sold only Schottky Diodes for scientific applications including radio astronomy and high frequency radar. During this period, VDI operated as a University of Virginia (UVa) spin-off and utilized the facilities at the University. Around 2001 VDI expanded to include offices in downtown Charlottesville, VA and started selling complete mixer, detector and multiplier products for 50-1000 GHz operation. By 2004 VDI started selling sub-systems such as THz Transmitter & Receiver modules. Also in 2004 all VDI operations moved to the 979 Second Street location in Charlottesville and VDI stopped utilizing UVa facilities. Since then VDI continued to grow the number of product offerings and employees needed to satisfy a broad range of terahertz and millimeter wave customers. Today, VDI employs over approximately 100 engineers, technicians and administrative staff working in a high tech 20,000 sq. ft. facility.
