Raytheon, an RTX (NYSE: RTX) business, has been awarded a three-year, two-phase contract from DARPA to develop foundational ultra-wide bandgap semiconductors, or UWBGS, based on diamond and aluminum nitride technology that revolutionize semiconductor electronics with increased power delivery and thermal management in sensors and other electronic applications. During phase one of the contract, the Raytheon Advanced Technology team will develop diamond and aluminum nitride semiconductor films and their integration onto electronic devices. Phase two will focus on optimizing and maturing the diamond and aluminum nitride technology onto larger diameter wafers for sensor applications. #military #defense #defence #militaryleak https://lnkd.in/g9bwEB58

Part 1 of 3 Exploring the Future of Military Technology with Gallium and EGaIn Tunable Filters As the defense sector continues to evolve, the demand for advanced communication systems and adaptable technologies is at an all-time high. Enter Gallium and EGaIn—liquid metal alloys that are revolutionizing the way we think about tunable filters in military applications. Why Gallium and EGaIn?  These remarkable materials offer unique properties such as: - High Electrical Conductivity: Ensuring efficient signal transmission. - Dynamic Tunability: Allowing real-time adjustments to frequency responses, which is crucial for communication in rapidly changing environments. - Lightweight and Flexible Design: Making them ideal for integration into various military devices without compromising performance. 🔧 Applications in Military Communications:  1. Tunable Microwave Filters: Enhance the performance of communication systems by enabling quick adaptation to different frequency bands, ensuring reliable communication in dynamic scenarios. 2. Reconfigurable Antennas: Improve operational flexibility, allowing for rapid changes in deployment strategies without the need for extensive hardware modifications. 3. Adaptive Signal Processing: Utilize liquid metals to create smart filters that can respond to electronic warfare tactics, ensuring secure and uninterrupted communication. As we push the boundaries of what's possible with military technology, the integration of Gallium and EGaIn into tunable filters represents a significant leap forward. The future of defense communication is not just about staying connected—it's about staying adaptable. Let's embrace innovation and lead the charge into a new technology! #MilitaryTechnology #TunableFilters #Gallium #EGaIn #Innovation #Defense #CommunicationSystems

The U.S. Defense Advanced Research Projects Agency (DARPA) has awarded BAE Systems’ FAST Labs™ research and development organization a $12 million contract for the Technologies for Heat Removal in Electronics at the Device Scale (THREADS) program. The DARPA THREADS program aims to overcome the temperature limits at the transistor scale inherent to power-amplifying functions. With new materials and approaches to diffusing the heat that degrades performance and mission life for monolithic microwave integrated circuits (MMICs), THREADS aims to resolve the thermal management challenges of today’s gallium nitride (GaN) devices. Many military systems leverage radio frequency (RF) electronics and have historically operated at powers well below their theoretical limits because the GaN transistors get too hot. Solving this challenge will improve the range of RF-based systems by nearly threefold. This will expand engagement distances for warfighters—taking them further out of harm’s way. BAE Systems will leverage its expertise and track record of developing and manufacturing advanced microelectronics for the program at its Microelectronics Center (MEC) located in Nashua, New Hampshire. The MEC is an accredited DoD Category 1A Trusted Supplier and manufactures GaN and gallium arsenide integrated circuits in production quantities for critical Department of Defense programs. Work on the THREADS program includes collaboration with Modern Microsystems, Penn State University, Stanford University, University of Notre Dame, and University of Texas at Dallas. #military #defense #defence #militaryleak https://lnkd.in/ghUhHhzq

Microchip Technology Inc. Adds Military-Standard Enhanced Low Dose Radiation Sensitivity (ELDRS) Qualification to Its Portfolio of Small-Signal Bipolar Junction Transistors to Ensure High Reliability for Critical Applications: The Joint Army Navy (JAN) transistors tested up to 100 Krad at 10 mrad per second   CHANDLER, Ariz., June 20, 2024 — In the United States the Defense Logistics Agency (DLA) manages the global defense supply chain and works with suppliers to ensure high reliability of all the components that go into an end application. Integral to the manufacturing process of components designed for military applications are rigorous tests and compliance standards that must be met to make it on the Quality Products List (QPL), which guarantees a certain level of reliability and streamlines the procurement process. As a leading supplier to the aerospace and defense market, Microchip Technology (Nasdaq: MCHP) announces its portfolio of JAN transistors is now tested and qualified to Military-Standard Enhanced Low Dose Radiation Sensitivity (ELDRS) requirements including MIL-STD-750, Test Method 1019 and specifications such as MIL-PRF-19500/255, /291, /355, /376 and /391. https://lnkd.in/edQhAUdi #news #pr #magazine #advertising #b2b #bannerads #magazine #newsletter #emailcampaigns #engineering #manufacturing #automation 

And yet another notable application of GaN emerges in the defense industry. The technology is revolutionizing the defense industry by offering significant advantages over traditional materials like gallium arsenide (GaAs) and silicon (Si). GaN-based components, such as transistors and amplifiers, provide higher power density, efficiency, and reliability. These qualities make GaN ideal for applications requiring robust performance in harsh environments, such as radar systems, electronic warfare, communications, and satellite systems. #GaN #GalliumNitride
