Profile: Virginia Diodes, Inc. designs, manufactures and sells millimeter wave and terahertz devices, components, and systems. Our products include detectors, mixers, frequency multipliers, and integrated systems for reliable operation at frequencies between 18 GHz and 2 THz. Our components include in-house fabricated GaAs Schottky diodes and microelectronic filter structures. We also provide mesh filters, comb generators, and radiometers for applications above 100 GHz. Our planar diodes are available as single devices or as multiple devices arranged in series, anti-series and anti-parallel configurations. We offer a broad range of millimeter-wave varactor and varistor mode frequency multipliers based on planar GaAs Schottky diode technology.
