Fri, Oct 14, 2022

Anritsu has introduced an LTE-V2X PSCCH TX measurement MX887068A-001 software option to enhance the cellular vehicle to everything (C-V2X) measurement function of universal wireless test set MT8870A / MT8872A.

The software supports the physical sidelink shared channel (PSSCH) for LTE-V2X (PC5) and supports RF measurement of the physical sidelink control channel (PSCCH). It also supports mass-production of LTE-V2X (PC5) devices for the evaluation of R&D RF test items.

LTE-V2X (PC5) will co-operate with the other radio access technologies such as 5G V2N (vehicle to network) and the Global Navigation Satellite System (GNSS) and is expected to be adopted for Connected Autonomous Vehicle applications.

Japan, Europe and China are investigating introduction of V2X to the New Car Assessment Program (NCAP). RF evaluation of V2X is becoming increasingly important from the safety aspect. V2X communications technology is used for dedicated short qrange communications (DSRC), such as intelligent transport systems (ITS). C-V2X using mobile communication technology with a wider communication range is also being investigated.

The Universal Wireless Test Set MT8870A/MT8872A series is designed for developing and mass-production various wireless communication equipment, modules, etc. Installing up to four high-performance test units in the main unit supports a seamless frequency band up to 7.3 GHz with a 200 MHz bandwidth.

Each unit measures independently in parallel, enabling the MT8870A to simultaneously evaluate multiple wireless communications devices.

Anritsu provides communications test and measurement equipment and supports customers to help develop wireless, optical, microwave / RF and digital solutions for R&D, manufacturing, installation and maintenance applications, as well as providing services for network monitoring and optimisation.

Anritsu also provides precision microwave / RF components, optical devices, and high-speed electrical devices for communication products and systems. The company develops solutions for 5G, M2M, IoT, as well as other emerging and legacy wireline and wireless communication markets.

NearStack PCIe improves connection to Open Compute project servers, says Molex

Thu, Oct 13, 2022

Direct-attached cable technology is used to improve signal integrity, lower insertion loss and reduce signal latency in Molex’s PCIe cable connection system for Open Compute project servers.

NearStack PCIe connector system and cable assemblies was developed in collaboration with members of the Open Compute Project to replace traditional paddle-card cable in an effort to optimise signal integrity and improve system performance.

The twinax termination eliminates the need for paddle cards within the cable assembly. Unlike competing cable jumpers, which are terminated by hand-soldering cables onto a PCB paddle card, NearStack uses a fully automated wire termination process. This high-precision process improves manufacturing efficiencies, repeatability and signal integrity, claimed Molex.

The NearStack PCIe is “ideal for next generation PCIe Gen 5 and Gen 6 system implementation,” said Bill Wilson, new product development manager, Molex Enterprise Solutions. “[It] is capable of 32Gbits per second NRZ data rates, enabling server OEMs to achieve unprecedented performance,” he said.

Molex has optimised the cable assemblies for efficient use of space as well as safe and easy attachment. Smart, rugged mechanical features, along with the optional “angle-exit” cable design, let engineers plug the jumpers into crowded boards to alleviating space constraints. NearStack PCIe also offers a low mated profile for improved airflow management and minimises interference with neighbouring components.

NearStack PCIe supports hybrid cables, with a NearStack PCIe connector on one end and legacy connector on the other, to facilitate integration.

The Open Compute Project is a consortium of industry leaders dedicated to combining the best available technologies into standardized hardware development with high-speed and high-bandwidth capabilities.

NearStack PCIe was defined and adopted as a standard by the Open Compute Project’s Small Form Factor (SFF) committee as SFF-TA-1026. The Open Compute Project (OCP) recommends the technology (TA-1026) for server reference designs.

NearStack PCIe also has been included in the OCP Modular – Extensible I/O (M-XIO) specification and the Modular – Full Width HPM Form Factor (M-FLW) as part of the next generation OCP Data Centre – Modular Hardware Systems (DC-MHS) family. As part of an open SFF standard, the technology is available to second-source vendors under license.

Molex will be exhibiting the NearStack PCIe at OCP 2022 (18 to 20 October) in San Jose, California, USA, Booth B1.

Invicta antenna extends Bluetooth, Wi-Fi and ZigBee coverage, says Antenova

Thu, Oct 13, 2022

Antenna and RF antenna modue manufacturer, Antenova, has released the Invicta compact antenna. It is for use with Wi-Fi, Bluetooth and ZigBee frequencies at 2.4 to 2.5GHz and averages 70 per cent efficiency across the 2.4GHz band.

The Invicta antenna averages efficiency of 70% across the 2.4 GHz band. Using this antenna allows designs to operate over longer distances and through walls and obstacles, said Antenova, extending the coverage and performance of wireless devices using Bluetooth, Wi-Fi and ZigBee.

It is a flexible printed circuit (FPC) antenna, which is easy to place in a design. It connects directly to the PCB via a cable and IPX MHF (UFL) connector. The antenna comes with 100mm cable as standard; other cable lengths and connector options are available on request.

An FPC antenna is different to an SMD antenna in that it operates independently to a ground plane length and no antenna matching is required, so the design cycle for Invicta is simpler and shorter, said Antenova.

The FPC antenna also makes for easier manufacturing, as the antenna is fixed in place by a simple self-adhesive strip. It can be curved and inserted into the case of a design. This style of antenna is suited to small to medium volume manufacturing.

Antenova has designed the Invicta antenna primarily for smart battery-powered devices for the home and office, where one single device provides global coverage. Typical applications in the home would be smart meters, home automation, wireless sensor networks, smoke and intruder alarms. It would also be used for remote monitoring in industrial and medical environments.

“The efficiency of an antenna is related to its size, with larger antennas usually providing better performance. The Invicta antenna . . . performs better than PCB trace antennas and provides exceptional performance and range in return for the relatively small space in a design,” said Antenova’s product marketing manager, Michael Castle.

The Invicta antenna part number is SRFW082.

Multi-protocol industrial Ethernet switch reduces system integration time

Wed, Oct 12, 2022

To address the connectivity needs of industrial and process automation, motion control, transportation, and energy automation, Analog Devices (ADI) has introduced the ADIN2299. This is a multi-protocol industrial Ethernet switch designed to operate in a star, line, or ring topology. It supports ProfiNet, EtherCat, EtherNet/IP and Modbus TCP.

The ADIN2299 contains a communications controller, a two port 10/100Mbits per second Ethernet switch, memory, physical layer (PHY) and protocol stacks. The ADIN2299 hardware, coupled with its software and pre-certified industrial protocols, reduces system integration time while providing fast time to market, claimed ADI.

Time to design and debug time is reduced through the provision of the protocol stack but also the RTOS, file system, drivers and TCP/IP. An application processor can connect to the switch platform via a UART, SPI or Ethernet interface.

The ADIN2299 software enables the application processor to connect to a unified interface so that various industrial protocols can be used without requiring any changes to the application processor software. This eliminates the learning curve associated with incorporating additional protocols, said the company. Customers can now leverage a single field device hardware design to support multiple industrial protocols.

For cybersecurity, the ADIN2299 has a secure boot and secure update feature which ensures that only verified code is executed to reduce possible disruptions from cyber attacks.

An ADIN2299 evaluation kit is available for platform assessment and system development. An application example is provided to demonstrate end-to-end, host-to-network and interface-to controller communication. Once an application development board is connected via UART, SPI, or Ethernet interface with the ADIN2299 evaluation board, protocol communication can be evaluated using a PLC or controller simulator. This allows for a complete verification before integrating the ADIN2299 into a system, confirmed ADI.

The small form factor ADIN2299 has supplied in a 194 CSPBGA package.

The ADIN2299 is in full production now.

Analog Devices provides a suite of analogue and mixed signal, power management, radio frequency (RF), and digital and sensor technologies, serving customers in the industrial, communications, automotive, and consumer markets.
