Recent advances in 3D printing technology now enable antennas and RF electronics to be designed and prototyped significantly faster than conventional manufacturing time scales. New multi-material 3D printers that …

DARPA GRYPHON developing high-performance microwave frequency source based on integrated photonics

September 28, 2021 Electronics & EW, Photonics Comments Off on DARPA GRYPHON developing high-performance microwave frequency source based on integrated photonics

In our information society, the synthesis, distribution, and processing of radio and microwave signals are ubiquitous in wireless networks, telecommunications, and radars. The current tendency is to use carriers in higher frequency bands, especially with looming bandwidth bottlenecks due to demands for e.g. 5G and the “Internet of Things.” “Microwave …

Militaries develop AI and machine learning enabled cognitive communications, Intelligence gathering and electronic warfare systems

September 26, 2021 AI & IT, Electronics & EW Comments Off on Militaries develop AI and machine learning enabled cognitive communications, Intelligence gathering and electronic warfare systems

Electronic warfare (EW) is one of the crucial aspects of modern warfare. EW receivers are passive systems that receive emission from various platforms that operate in the relative vicinity. The received signals are typically analyzed to obtain valuable information about characteristics and intentions of various elements that are presented in …

Hybrid marine propulsion system technology for smart ships

September 25, 2021 Electronics & EW, Energy & Propulsion Comments Off on Hybrid marine propulsion system technology for smart ships

Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. At present, 90% of the sea-going naval ship are diesel-powered. To achieve the safe upper limit for global warming of 1.5 degrees Celsius, ‘all ships designed and built today must operate in …

Millimeter wave (mmWave) power amplifiers enable mmWave Radios for 5G and Satellite Communications

September 16, 2021 Comm. & NW, Electronics & EW, Energy & Propulsion Comments Off on Millimeter wave (mmWave) power amplifiers enable mmWave Radios for 5G and Satellite Communications

Millimeter waves are electromagnetic signals with frequencies ranging from 30 to 300 GHz that correspond to wavelengths of 10 to 1 mm in the free space. Electromagnetic waves in the millimeter-wave band (with frequencies between 30 and 300 GHz, or wavelengths between 10 and 1.0 mm) have attractive characteristics. One of …

However, resource constraints across these organizations can limit …

New thermal Management technologies for Mission-Critical Military Ground, Sea, Air and Space systems

August 26, 2021 Electronics & EW, Energy & Propulsion, Management, Manufacturing Comments Off on New thermal Management technologies for Mission-Critical Military Ground, Sea, Air and Space systems

The performance of electronics degrades as temperature increases from the ambient temperature. The temperature of a device increases when the device is on since no system operates at 100% efficiency. Output power is not equal to the power fed to the device, and the difference between this is power loss. …

Electronic thermal management materials (ETMM) ensure performance and reliability for Mission-Critical Military Ground, Sea, Air and Space systems
