SUB-5MW, IEEE 802.15.4Z ULTRA-WIDEBAND TRANSMITTER CHIP I
mec has developed an IEEE 802.15.4z impulse-radio ultra-
wideband (IR-UWB) transmitter chip. Fabricated in 28nm CMOS (with an occupied core area of only 0.15mm²), it has been custom- developed to achieve a record-low power consumption of 4.9 milliwatt (mW) in a standard-compliant operation. It is also the first sub- 5mW IR-UWB transmitter chip to comply with the newly released IEEE 802.15.4z standard for even more
accurate and secure UWB ranging measurements. The chip’s digital polar
transmitter architecture reduces the IC’s power consumption to only 4.9mW. Additionally, injection- locked ring oscillator (ILRO) technology allows even greater power savings – by enabling fast duty cycling between the IR-UWB transmitter’s signal bursts and within a packet, allowing parts of the transmitter to be turned off
between those pulses. The chip complies with the
worldwide spectrum regulations that dictate in which frequencies the UWB transmitter can emit – as to avoid interference with other wireless services. To that end, the imec researchers propose an asynchronous pulse shaping design that meets the international spectral emission regulations in the 3-10GHz bands.

RENESAS AUTOMOTIVE SOC FUNCTIONAL SAFETY TECHNOLOGIES
Renesas Electronics has developed processor technologies for automotive systems-on-chip (SoCs) used in applications such as advanced driver assistance systems (ADAS) and autonomous
driving (AD) systems that aim to optimise both performance and power efficiency while supporting a high level of functional safety. This development includes a convolutional neural network (CNN) hardware accelerator core that delivers 60.4 trillion operations per second (TOPS) and a power efficiency of 13.8 TOPS/W along with safety mechanisms for fast detection of and response to random hardware failures. This makes it possible to create a highly power efficient detection mechanism with a high failure detection rate. A mechanism has also been integrated that allows software tasks with different safety levels to operate in parallel on the SoC without interfering with each other, thereby bolstering functional safety for ASIL D control. These technologies have been applied in the company’s latest R-Car V3U automotive SoC.

NEW 5G RF REGULATORY TEST SYSTEM W
elcome to the February issue, in which we bring
you a focus on a B2B digital platform that offers a solution for minimising spare parts costs on p8. We speak to Anders about how the pandemic has forced electronic manufacturers and their suppliers to re-examine their processes and find new ways to make business work on p10. In our cover story, Rochester Electronics discusses its end- to-end support for the complete RF chain on p12. Cressall explores the top considerations when designing an effective enclosure on p14, plus much more of the latest products and components tech. Michelle Winny Editor

spurious tests and interference tests, which are difficult for customers to build their own test environment. The
Anritsu Corporation has released a new RF Regulatory Test System ME7803NR solution for regulatory compliance testing of 5G communications systems. The new test system uses Radio Communication Test Station MT8000A as a simulated 5G NR base station in combination with a spectrum analyser and signal generator to implement ARIB/ETSI/FCC-compliant FR1 RF tests. In addition, the measurement
efficiency and quality of 5G terminals are assured by the easy-to-operate GUI and built-in calibration function for improved reliability. It is a platform that can perform
ME7803NR makes it easy to evaluate whether the RF performance of 5G terminals meets regulatory requirements as well as simplifies evaluation of whether radio-waves are being used efficiently or not, helping 5G market penetration. Anritsu expects its new ME7803NR
to play an important role in deploying commercial 5G mobile network services by facilitating the spread of 5G terminals. The RF Regulatory Test System
ME7803NR supports FR1 RF regulatory compliance tests of 5G NR terminals.
