Founded in Cleveland in 2006, Teraphysics is an R&D company developing and commercializing patented, miniaturized millimeter-wave traveling-wave-tube amplifiers. Its business-card-sized devices are designed to deliver tens to hundreds of watts of linear power across frequencies from roughly 70 to 650 GHz, supporting advanced communications and electromagnetic-spectrum applications. The company’s technology grew from work by former NASA engineers and physicists who collaborated at NASA Lewis, now NASA Glenn, in the 1990s.
B&Z TechnologiesFor more than 30 years, B&Z Technologies has designed and manufactured microwave and millimeter-wave amplifiers, including units built for operation at cryogenic temperatures. Based in East Setauket, the company combines discrete-transistor, miniature-element and air-line designs in a common chassis platform that can be adapted to customers’ electrical and mechanical requirements. Its catalog includes ready-to-ship models, while its engineers also modify existing designs or create new amplifiers for demanding applications.EAST SETAUKET, NY
TeraProbes, IncFounded in 2014 as an Ohio State University research spin-off, TeraProbes develops fully automated, contact-free systems for testing high-frequency electronic devices and integrated circuits on wafers. Its proprietary probing technology uses focused high-frequency beams and tiny on-wafer antennas rather than physical contact, while its robotic systems also characterize materials across millimeter-wave and terahertz bands. The Hilliard company’s technical leadership remains closely tied to university research, with its president, CEO, and CTO each holding PhDs and academic appointments.HILLIARD, OH
