A new phase-noise measurement system for “power users” helps optimize and prove the performance of new designs, meet operational requirements, as well as remain on schedule and on budget. Phase noise is an unwanted phase modulation noise that emerges in nearly all radio frequency and microwave devices including oscillators, mixers, dividers, multipliers and amplifiers. Power […]
Economical digital microscope includes built-in LCD for standalone PCB inspection
The Saelig SAE106S Digital Microscope is a versatile tool designed specifically for PCB inspection, but can also prove to be useful in many other fields such as coin or mechanical part examination. The SAE106S may be used as a standalone inspection device for circuit board examination using its built-in 4.3-in LCD screen or it may […]
Economical vector signal generator features 40 MHz bandwidth
The VSG60A vector signal generator offers the performance and agility of a serious vector signal generator at a fraction of the cost. A low phase noise, agile local oscillator with a 200 μsec switch time enables frequency hopping spread spectrum testing, and a dual 14-bit DAC runs at 2x or 3x the I/Q symbol rate […]
Spectrum analyzer features 20 GHz bandwidth, 160 MHz IBW of calibrated I/Q capture
The new SM200B spectrum analyzer offers 160 MHz instantaneous bandwidth (IBW) calibrated I/Q capture, available through block transfer of a two-second I/Q buffer over USB 3.0 to the PC. This added 2-seconds of segmented I/Q capture memory, with advanced triggering options such as frequency mask triggering (FMT) plus user-specified pre- and post-trigger, satisfies the ever-increasing […]
Why it’s tough to characterize SiC power MOSFETs
Switching transients and parasitics can combine to thwart the accurate measurement of important MOSFET operating parameters. Levi Gant, Xuning Zhang, Ph.D., Littelfuse, Inc. Silicon carbide (SiC) power MOSFETs get a lot of attention because they can switch fast while maintaining high blocking voltages. But their superior switching qualities also have potential drawbacks. Parasitic inductances caused […]
Audio codecs excel at noise cancellation, low power consumption
The DA740x is a family of highly-integrated audio codec chips that deliver best-in-class active noise cancellation (ANC), providing optimal audio performance in any environment to the rapidly-growing wireless headphones market. The DA740x supports feedforward and feedback ANC topologies in which the noise canceling microphones sit either outside or inside the headphone cup. With its integrated […]
5G technology said to usher in new generation of robots
The 5G technology that is on the horizon is being described as a once-in-a-generation technological advent. The massive capacity, ultra-low latency, and high reliability of 5G communications will enable entire new ecosystems of connected technologies to flourish. In the field of robotics, this will mean everything from highly precise industrial robots that can be controlled […]
New from the research lab: High-energy textile lithium battery
Researchers at The Hong Kong Polytechnic University (PolyU) say they have developed a highly flexible, high-energy lithium battery for wearable electronics with a myriad of applications. PolyU’s novel lightweight Textile Lithium Battery demonstrates an energy density of more than 450 Wh/L and flexibility — with a bending radius of less than 1 mm and foldability […]
Gallery: An inside view of the STM32WB workshop
STMicroelectronics is putting on a series of one-day free workshops that deal with programming its new STM32WB, a dual-core multi-protocol wireless microcontroller that combines Bluetooth 5.0, OpenThread, and ZigBee 3.0 connectivity. We sat in on the well-attended session held in Cleveland, Ohio. Here’s a few of the things you’ll experience if you sign up for […]
