Mouser Electronics and Grant Imahara launch 2019 Empowering Innovation Together Series, “Engineering Big Ideas”
Mouser Electronics Inc. and celebrity engineer Grant Imahara join forces for the fifth consecutive year in this latest edition of the award-winning Empowering Innovation Together series: Engineering Big Ideas. To watch the first video, go to https://youtu.be/VRrqHSJFqlM. This four-part series will explore the process of turning an idea into a product and examine the path to […]
What are cryogenic temperature measurements? Part 1
Cryogenic temperatures may seem only of limited interest, but they are actually critical in many instrumentation and other systems. Measuring these ultralow temperatures is both easy and difficult, depending on temperature, material, and mass. Temperature is the most commonly measured physical variable, whether it’s just to assess the local weather to manage the performance of […]
Autonomous vehicle sees with LiDAR eyes
Automakers are struggling to deliver the first commercially available fully autonomous car (SAE Level 5). There are a lot of vision technologies and sensors available, but fine-tuning them has proved to be challenging. Cars need to “see” objects, moving or stationary, from far away enough to react and make driving decisions. One of the most […]
How bidirectional converters speed the design of dual-battery automotive systems
New standards for combined 48-V/12-V vehicles dictate stringent tests for overvoltages and currents that new converter ICs can help meet. Tony Armstrong | Analog Devices Inc. The 48/12-V automotive battery system is just around the corner. Most major automobile manufacturers have been perfecting such systems for past few years, and it is evident that their […]
Inertial Measurement Units: The hidden key to Apollo success, now a MEMS device (Part 2)
Part 1 of this article looked at the classic, highly refined, mature gyroscope-based IMU used for the Apollo moon mission; this part looks at the very different technologies which have largely replaced it. Gyro-based IMU: obsolete, or not? Inertial navigation relies on a stable platform with an orientation which is fixed in space and maintains […]
RF Switches, Part 2: Analog and MEMS switches
Part 1 of this FAQ looked at the venerable electromechanical RF switch – still widely used in some applications, where it is the only viable option – and use of PIN diodes as RF switches. This part looks at analog and MEMS-based switches. Q: What is an analog switch? A: It’s conceptually straightforward: in basic […]
RF switches, Part 1: Mechanical and PIN-diode switches
There’s a ubiquitous and increasing need to switch RF signals ranging into the tens of GHz; four basic switch technologies – electromechanical, PIN diode, analog, and MEMS – are available, each with different features and capabilities. The need to switch RF signals has been a necessary design function since the earliest days of “wireless.” This […]
Multi-channel, mixed-signal RF converter platform boosts call capacity, data throughput for wireless carriers
Analog Devices, Inc. introduced a mixed-signal front-end (MxFE) RF data converter platform that combines high-performance analog and digital signal processing for a range of wireless equipment such as 4G LTE and 5G millimeter-wave (mmWave) radios. ADI’s new AD9081/2 MxFE platform allows manufacturers to install multiband radios in the same footprint as single-band radios, which as […]
Impedance/Ppotentiostat Analog Front End handles biological, chemical sensing
Analog Devices, Inc. announced a new electrochemical and impedance measurement front end that enables the next generation of vital sign monitoring devices and intelligent electrochemical sensors. The AD5940 analog front end incorporates both potentiostat and electrochemical impedance spectroscopy (EIS) functionality on a single chip, allowing for sensor measurement in both time and frequency domains. The […]
