Roku bills its new Ultra device as its fastest and most powerful player ever. Its features include 50% more range for its wireless capabilities, support for Dolby Vision (an HDR standard), Dolby Atmos (a surround-sound format), and Bluetooth, a fast channel launch, a lost remote finder capability, voice-remote controls and personal shortcut buttons, and the […]
Compact dc electronic loads measure voltage, current, calculate power
The Keysight EL30000 Series bench dc electronic loads offer a compact bench form factor with a built-in data logger that delivers insights for immediate, real-time decisions, and minimizes the need for additional instruments with an accurate system that measures voltage, current and calculates power. An electronic load is an instrument designed to test sources by […]
Certification tool checks out last-mile fiber deployments
The VIAVI Optimeter is a new type of network test tool to speed and simplify last-mile optical fiber activation and maintenance. As the leading fiber test and measurement supplier, VIAVI is focused on helping communications service providers (CSPs) and contractors improve first time install completion rates for faster service activation and revenue. It’s estimated that […]
750-V SiC FETs feature reduced on-resistance, low intrinsic capacitance
Devices based on an advanced Gen 4 SiC FET technology platform are the first and only 750-V SiC FETs currently available on the market. These Gen 4 devices enable new performance levels, based on leadership Figures of Merit (FoM), that benefit power applications across automotive, industrial charging, telecom rectifiers, datacenter PFC, and dc-dc conversion as […]
IEDM highlights: Vibration-energy harvester on a chip
A MEMs device generates enough power to run a typical GPS IC Researchers at the University of Tokyo have come up with microelectromechanical systems (MEMs) vibrational energy harvester that yields a maximum power of more than 1.2 mW from environmental vibrations of 0.65 G (1 G = 9.8 m/sec2) at 158 Hz. The device works […]
Catalog update covers passive components, optoelectronics and power modules
With “Electronic Components 2020/2021” Würth Elektronik publishes an updated supplement to its general catalog. Besides a series of innovative new products, there is background and basic knowledge about EMC for high-frequency applications, gate driver circuits, single pair Ethernet, laser and infrared LEDs, as well as additional information. Practical application examples support the use of the […]
IEDM highlights: GaN HFETs get a p-channel version that operates at gigahertz speeds
Researchers at Cornell University and Intel Corp. say they’ve devices a wide-bandgap p-type transistor counterpart of the n-channel GaN HFET. In a paper to be presented at the upcoming IEDM conference (Paper #8.3, “GaN/AlN p-Channel HFETs with I max >420 mA/mm and ~20 GHz f T /f MAX ,” K. Nomoto et al, Cornell University/Intel), […]
IEDM highlights: A 2D lidar on a chip
Samsung researchers have advanced the concept of a solid-state lidar with the development of a single-chip device with a 10-m range. Light Detection and Ranging (lidar) technology normally requires flash illumination or beam scanning to detect surroundings. The problem is such schemes generally demand use of a high-power laser. So most commercially available long-range lidar […]
Good-bye x-ray tubes, hello “vacuum” transistors
Among the presentations at this year’s IEDM: A silicon vacuum transistor that operates at over 38 kV. Examine a hospital x-ray machine or a high-power RF transmitter and you’ll find a beefy vacuum tube. Vacuum devices still rein for applications requiring extremely high voltages (>30 kV) such as for x-ray generation or high-power radar (> […]
Laptop-based instrument records wireless environment and motion for playback in testbeds
Tracker is a Wi-Fi test solution that enables recording of an environment such as a house for playback in the octoBox personal testbed. Mesh Wi-Fi deployments with multiple access points, either in the home or in the office have unique challenges related to motion that require optimization. To operate well, it is important that Wi-Fi […]
