ujitsu Components Europe is celebrating one hundred years of


manufacturing relays this year. The Takamisawa Electric Company was


understanding of mechanical and electrical engineering, product design, and material science to select materials for housing, contacts, actuators, etc.," explains Hans Grobben, VP of Marketing & Sales at Fujitsu Components Europe.” As well as partnering with customers on relay choice, the


company also excels in features to ensure quality and long operational life. Fujitsu is investing in new, fully automated production lines for the most popular relays and to meet the increasing demand for new, high voltage, high current DC relays that are required for the growing markets of electric and hybrid vehicles as well as for renewable energy. Fujitsu is one of the leaders in DC


relay design and manufacturing, which present new design


challenges, such as one way metal transfer between the contacts that does not occur with AC current due to the constantly changing direction of the current. This is just one example of how each switching operation results in wear of the relay, a fact that Fujitsu takes into account when guaranteeing a minimum number of operations; figures that Fujitsu verifies by extensive real life testing. emea.fujitsu.com/components

This time, Rohm has developed an audio SoC that acts as the ‘brain’ of audio devices along with a reference design that improves audio quality for the entire system while minimising development load.


processor chip with SDRAM featuring an optimised architecture that leverages software and circuit elements such as ASIC (Application Specific IC), MCU, and various media decoders (developed by the Rohm Group) on a single chip. The media decoder supports a wide range of audio sources, and utilising over 20 years of expertise allows the company to ensure stable playback of damaged CDs and even non-standard USB. In addition, SDRAM is built in that contributes to greater miniaturisation. www.rohm.com


PPM Power has signed an agreement with Japanese manufacturer SanRex to distribute their power semiconductor modules in the UK. As well as the new silicon carbide (SiC)based MOSFETs, SanRex also manufacture schottky diodes and thyristor modules operating up to 2200 Volts and 500Amps. Typically these power modules are used in applications such as welding, induction heating, motor drives, battery chargers and grid connected inverters. “Silicon Carbide MOSFETs have

Keysight Technologies, Inc. has announced that its pre-5G modulation analysis option, available in its latest 89600 VSA software release, will include standard-compliant 5G new radio (NR) measurements upon the 3GPP 5G NR standard’s release. Pre-5G is a 5G radio specification


published by Verizon Wireless, in cooperation with partner companies. The specification targets fixed wireless access at 28-GHz frequencies for initial trials and deployments. Keysight’s new 89600 VSA provides


comprehensive time, frequency, and modulation domain analysis for pre-5G signals based on the Verizon 5G open trial specification. The software allows configuration of result traces (e.g., acquisition time and spectrum) and pre-5G specific modulation quality metrics and traces for quick and easy identification of signal characteristics. The software also helps troubleshoot intermittent error peaks and repeated synchronisation failures. 3GPP 5G NR is the emerging global


5G standard. The specification is expected to be included in Release 15 of the 3GPP standard, which is due out in 2018. With Keysight’s new 89600 VSA software release, early adopters can design and verify performance to the draft specification now, before it is published, and be fully prepared to work with the official standard once it is available. Using 89600 VSA, designers can


make EVM and other signal quality measurements of 3GPP 5G NR-like signals. Measurements for DFT-spread orthogonal frequency-division multiplexing (OFDM) (SC-FDMA) and CP-OFDM are made using a custom OFDM modulation analysis application. The software’s close link to the Keysight EEsof EDA SystemVue simulation environment gives designers even more flexibility when working with the draft specification. Once 3GPP Release 15 is officially


published, Keysight will enhance the 89600 VSA software and its pre-5G functionality with standard-compliant 5G NR measurements. www.keysight.com/find/5G


offered compact, high speed, very low loss power switching for a while now,” says Phil Surman – Sales Director at PPM Power. “SanRex have developed their own best-in-class die technology as well as compact, rugged transfer-moulded packages that deliver the next leap in performance at a system level. With silicon carbide MOSFETs and silicon based diode modules from SanRex, PPM Power now has semiconductor product offerings for mainstream power electronics as well as very high performance applications.”


www.ppm.co.uk A comprehensive hardware and


software platform solution has been announced by Intel to enable faster deployment of customised field programmable gate array (FPGA)- based acceleration of networking, storage and computing workloads. Complex data-intensive applications in the areas of genomics, finance, industry 4.0 and other disciplines are pushing the boundaries of data centre capabilities. Intel FPGA-based acceleration exploits massively parallelised hardware offloading to maximise performance and power efficiency of data centers. The new solution abstracts the complexities of implementation to enable architects and developers to quickly develop and deploy power-efficient acceleration of a variety of applications and workloads.
