New De-embedding Capabilities Allow for More Accurate High-frequency DUT Performance Validation
Anritsu Company introduces the Universal Fixture Extraction (UFX) option for its VectorStar® vector network analyzers (VNAs) to provide signal integrity and on-wafer engineers with an increased range of on-wafer and fixture calibration choices, even when a full set of calibration standards is not available. Developed to address the design challenges associated with the high-frequency, high data rate requirements of 4G and emerging 5G systems, as well as backhaul and data centers, UFX features unique analysis tools so engineers can more accurately and efficiently evaluate designs. http://bit.ly/2s72VKS
Mouser to Stock Micro Crystal’s RTC Modules and Eval Boards
Mouser is now stocking Micro Crystal’s Real-Time Clock modules, which combine a 32.768 kHz tuning fork crystal resonator with a CMOS-based oscillator and RTC integrated circuit, perfectly factory calibrated inside a miniature ceramic SMD package. Each module is designed to address the demand for high accuracy, temperature compensation, and ultra-low current consumption. The modules provide standard clock and calendar functions and are available in tolerances from 2ppm to 20ppm with options including I2C or SPI interface, alarm, interrupt, power management, RAM / EEPROM memory, extended operating temperature range up to 125 degrees Celsius, and AEC-Q200 automotive qualification. Mouser is also stocking evaluation boards, which include corresponding RTC modules for facilitated evaluation. http://bit.ly/2rnOpBk
Award Winning Technology Author Bill Schweber Writes:
Designers of handheld and portable wireless products such as smartphones and wearables rely on tiny chip, patch and trace antennas that can be placed within the device. While these miniature devices solve the problem of bringing multiband antenna arrays to small form factor systems, they also introduce issues related to reduced radiation efficiency, impedance matching, and interaction with nearby objects and bodies.
To address these problems, designers are being armed with new design and circuit techniques to make these antennas more than just a standalone component. Instead, they are becoming part of a dynamic antenna subsystem that mitigates many of these design challenges. This shift in design requires extensive simulation and analysis, which is being addressed by constantly improving field solver software. http://bit.ly/2s6ZqEw
Coilcraft has introduced its new 0201HL Series of chip inductors available in seven inductance values ranging from 22 to 51 nH, the highest currently offered in a wirewound 0201 package. This inductance range is fully optimized for impedance matching in 700 MHz LTE and 5G applications. http://bit.ly/2s74yIE
Digi-Key Editor, Art Pini, Explains: To meet efficiency and form factor requirements, switched-mode power supply manufacturers are incorporating new semiconductors and circuit topologies, while also adhering to higher standards of power integrity. As a result, designers must make more complex measurements of switched-mode waveforms, which increases test time and adds cost.
In an effort to reduce test time, test equipment makers have developed hardware and software that work together to automate many of the functions and complex analysis. A good example of this combination is the Teledyne LeCroy HDO4104 oscilloscope with Power Analyzer software. This article will describe how the two can be used to perform critical analyses to shorten power supply development and test. http://bit.ly/2qxAIvZ
Expansion Connector Sample Kits for Makers
Samtec proudly announces the release of four unique Expansion Connector Sample Kits for Makers. These new kits allow continued growth and stacking of the most popular electronics platforms using standard 0.100” (2.54mm) centerline IDC cables, sockets and headers. http://bit.ly/2rnBC1I
Developers have had access for some time to MCUs that feature low-power operating states, shutting down peripherals and even the core itself to reduce system power requirements. For some applications, however, developers need more direct control over power utilization to ensure that portions of the system remain powered to meet key functional requirements. http://bit.ly/2qxcwtL
D3 Semiconductor, a company bringing together affiliated semiconductor companies and top-talent experts, announces that Mouser Electronics is now its global distribution partner. According to the agreement, Mouser is stocking D3 Semi’s full product line of +FET™ line of 650V-rated superjunction MOSFETs, which exhibit best-in-class performance in hard–switched applications such as PFC boost and inverters used in telecom, enterprise computing, UPS and solar. http://bit.ly/2qxiIlr
Designing an Internet-connected product requires many skillsets. Developers need to know how to write embedded software, build a circuit board, understand how to secure their device, and connect to a network to remotely update and manage their device. Building out the expertise and the infrastructure for a single IoT product can be challenging, time consuming, and expensive. Development teams require a way to jumpstart their development and minimize what they need to do in a typical design cycle in order to meet cost and time-to-market requirements. http://bit.ly/2qx4ktm
Coilcraft’s new SRT8045 Series of magnetically shielded power inductors offer superior performance and a smaller package than previous-generation products. Measuring just 8.0 x 8.4 x 4.5 mm, the highly cost-effective SRT8045 has saturation current ratings up to 17.4 Amps and DC resistance as low as 7.7 mΩ, allowing users to dramatically reduce inductor size while maintaining excellent performance. http://bit.ly/2psooem #techwireintl
