Microsemi announced six new monolithic microwave integrated circuit (MMIC) products, including four wideband low noise MMIC amplifiers (MMA040AA , MMA041AA, MMA043AA and MMA044AA) and two wideband gallium arsenide (GaAs) MMIC switches (MMS006AA and MMS008AA). The new MMIC products are ideally suited for test and measurement, electronic warfare and radar applications.

The successful development ofRenesas Electronics' Split-Gate Metal-Oxide Nitride Oxide Silicon (SG-MONOS) flash memory cells has been announced, employing transistors with fin-shape for use in microcontrollers (MCUs) with on-chip flash memory having a circuit linewidth of 16 to 14nm or finer.SG-MONOS technology is reliable for use in automotive applications.

The second most-produced organic chemical in the world, propene is a key component of plastics found in consumer goods such as electronics, clothing and food packaging.For years, oil refineries have produced an abundance of the compound through the “steam cracking” process that converts oil-derived naptha into useful components. In the last decade, however, many U.S. refineries have instead moved toward shale gas cracking as domestic ...

Co-founder and Chief Technology Officer of GaN Systems, John Roberts, will deliver the keynote address at the 4thIEEE Power Electronics Society Workshop on Wide bandgap Power Devices and Applications (WiPDA).

The Keithley S540 Power Semiconductor Test System, a fully-automated, 48 pin parametric test system for wafer-level testing of power semiconductor devices and structures up to 3kV has been released by Tektronix. Optimised for use with the latest compound power semiconductor materials including silicon carbide (SiC) and gallium nitride (GaN), the fully integrated S540 can perform all high voltage, low voltage, and capacitance tests in a single pro...

Scientists at The University of Manchester have discovered a method of creating optoelectronic circuits using graphene and other 2D materials that are much smaller than their current counterparts.Optoelectronics, the technology that uses pulses of light rather than traditional electrical signals, is vital for telecommunication networks.Modulators are important in optoelectronic circuits as they control the signals passed through optoelectronic de...

A highly-efficient, nanoparticle-based method for heating water and generating water vapor from sunlight is demonstrated by WPI-MANA scientists.Solar energy could provide a renewable, sustainable source of power for our daily needs. However, even the most state-of-the-art solar cells struggle to achieve energy conversion efficiency of higher than 30%. While current solar-powered water heaters fare better in terms of energy efficiency, there are s...

Powerful electronic components can get very hot. When many components are combined into a single semiconductor chip, heating can become a real problem. An overheating electronic component wastes energy and is at risk of behaving unpredictably or failing altogether. Consequently, thermal management is a vital design consideration.This becomes particularly important in devices made from gallium nitride.

Panasonic Automotive & Industrial Systems Europe announced its technology line-up for electronica 2016, taking place November 8th – 11th in Munich, Germany. At Stand 105 in Hall B6 the company will be highlighting industry-leading innovations — including GaN semiconductors, thermal management products, batteries for industrial use, passive components, sensors, electromechanical, as well as automotive solutions.

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory have for the first time created a single device that acts as both a laser and an anti-laser, and they demonstrated these two opposite functions at a frequency within the telecommunications band.Their findings, reported in a paper to be published in the journal Nature Photonics, lay the groundwork for developing a type of integrated device with the flexibility to operat...
