A Teledyne Technologies business has unveiled two new ruggedized gallium nitride, high electron mobility transistors designed for high-reliability space, avionics and military applications. The 30-amp TDG650E30B and 15-amp TDG650E15B GaN HEMTs are the latest additions to Teledyne e2v HiRel’s family of 650-volt products based on GaN Systems’ technology.

Raytheon has exhibited at the Association of the U.S. Army’s annual conference its proposed radar for the Army’s Lower Tier Air and Missile Defense Sensor program meant to replace the Patriot air-and-missile defense radar system. C4ISRNET reported Monday.

Lockheed Martin has selected Qorvo to provide gallium nitride power amplifiers for a U.S. Army-employed phased array radar.

Lockheed Martin conducted a series of exercises to demonstrate how its radar platform will meet the U.S. Army’s requirements for the Lower Tier Air and Missile Defense Sensor during the service’s “sense-off” at White Sands Missile Range in New Mexico.

Northrop Grumman develops gallium nitride and other semiconductor materials for integration with radars, sensors and other electronic warfare systems to support warfighters as they operate in the multidomain battlespace. The company said Wednesday it produces GaN and other semiconductors through its advanced technology laboratory, which runs as a Pentagon trusted foundry and has delivered over 8M components used to support missions across maritime, space and other domains.

Lockheed Martin has received a contract modification to incorporate gallium nitride into U.S. Army radars used to protect soldiers from indirect fire. The company said Monday updating the AN/TPQ-53 radar technology with GaN can help increase the system’s performance to acquire counterfire targets. AN/TPQ-53 is designed to help military users detect, classify, track and identify the location …

Raytheon has secured a $14.9 million contract from the U.S. Air Force Research Laboratory and Office of the Secretary of Defense to further develop the production process of gallium nitride-based semiconductors. The company said Wednesday it will work to update the performance, supply and the dependability of wideband, monolithic, microwave-integrated circuits and circulator …

Raytheon has received a contract modification from the Missile Defense Agency to develop a transition-to-production process that will incorporate Gallium Nitride components onto existing and future AN/TPY-2 radars. The company said Friday the initial effort will also support efforts to modernize ballistic missile defense radars through the transition from Gallium Arsenide to GaN technology …

Raytheon will collaborate with the U.S. Army Research Laboratory to develop modular building blocks for the service branch’s Next Generation Radar program under a two-year, $1.1 million cooperative research agreement. The partnership aims to explore approaches to design and fabricate modular components for integration into the NGR’s open architecture and address flexibility, agility and efficiency requirements across radar bands, Raytheon …

Boeing and Lockheed Martin have submitted proposals to the U.S. Air Force to build the next batch of GPS III satellites for the service branch, Aviation Week reported Tuesday. Jen DiMascio writes Northrop Grumman also submitted a bid to compete for the satellite production contract. The service branch intends to …

Cobham will integrate the gallium nitride technology of RFHIC Corp. in South Korea into the former’s radio-frequency products as part of a new strategic partnership. The companies will jointly build GaN high-power amplifier modules set for installation in a prototype 175-kilowatt solid-state transmitter, Cobham said Wednesday. Bob McArthur, vice president for …
