RTX, DARPA to Revolutionize Gallium Nitride Technology for Improved Radio Frequency Sensors
November 17, 2023 | Raytheon CompanyEstimated reading time: 1 minute
Raytheon, an RTX business, has been awarded a four-year, $15 million contract from DARPA to increase the electronic capability of radio frequency sensors with high-power-density Gallium Nitride transistors. The improved transistors will have 16 times higher output power than traditional Gallium Nitride with no increase in operating temperature.
Raytheon is the world's leading manufacturer of military-grade Gallium Nitride, a cutting-edge semiconductor technology that, when used in radar systems, improves range and radar resource management handling. This new prototyping work is being performed under DARPA's Technologies for Heat Removal in Electronics at the Device Scale program, known as THREADS.
"Our engineers have unlocked a new way to produce Gallium Nitride, where thermal management is no longer a limiting factor," said Colin Whelan, president of Advanced Technology at Raytheon. "These new system architectures will result in sensors with enhanced range."
Raytheon is partnering with the Naval Research Laboratory, Stanford University and Diamond Foundry to grow diamond, the world's best thermal conductor, for integration with military-grade GaN transistors and circuits. Cornell University, Michigan State University, the University of Maryland and Penn State University are also providing technology and performance analysis.
For nearly 25 years, Raytheon has invested in Gallium Nitride research and development, using it in defense systems like the Patriot®, LTAMDS/GhostEye family of radars, APG-79(v)4 and SPY-6 family of radars.
Work on this contract is being conducted in Andover, Massachusetts.

SMT Perspectives and Prospects: Critical Materials—A Compelling Case, Part 3
01/17/2024 | Dr. Jennie Hwang -- Column: SMT Perspectives and ProspectsNew tumultuous forces involving geopolitical pull and technological and market push have emerged since I published the first two parts of this topic in February and May 2022, respectively. Here, I will consider the impact of these new forces. Critical materials and minerals that are the foundation for essential goods have long been sourced from areas with wars or near-wars and some unfriendly nations; this causes high-risk concerns.
Pete Starkey’s Five Must-Reads of 2023
12/27/2023 | Pete Starkey, I-Connect007I must say, this has been a good year. We were free at last from COVID travel restrictions and obligatory face masks. This means I have been able to get out and about, network with colleagues in the industry, and report on some notable presentations from distinguished technical specialists in Europe. It has been a difficult job choosing a “top five” from such a multiplicity and diversity of high-quality papers, but here’s my selection.
