Mixed-signal RF converter caters for 4G LTE and 5G mmWave radios

Thu, Jun 13, 2019

A mixed-signal front-end (MxFE) RF data converter from Analog Devices combines analogue and digital signal processing (DSP) for wireless equipment such as 4G LTE and 5G millimeter-wave (mmWave) radios. The AD9081/2 MxFE platform allows manufacturers to install multi-band radios in the same footprint as single-band radios, which can triple call capacity of today’s 4G LTE basestations. The 1.2GHz channel bandwidth RF data converter also enables wireless carriers that have additional antennae to cell towers to meet the higher radio density and data rate requirements of emerging mmWave 5G, adds Analog Devices.

The AD9081 and AD9082 provide software configurability to allow designers to customise radios as frequency translation and filtering moves to the digital domain.

The AD9081 and AD9082 MxFE converters integrate eight and six RF data converters, respectively, which are manufactured using 28nm CMOS process technology.

The MxFE platform processes more of the RF spectrum band and embeds DSP functions on-chip to enable the user to configure the programmable filters and digital up and down conversion blocks to meet specific radio signal bandwidth requirements. This results in a 10X power reduction compared to architectures that perform RF conversion and filtering on the FPGA, while freeing up valuable processor resources or allowing designers to use a more cost-effective FPGA.

Both MxFE options achieve the industry’s widest instantaneous signal bandwidth (up to 2.4 GHz), according to Analog Devices. This simplifies hardware design by reducing the number of frequency translation stages and relaxing filter requirements. This level of integration lowers chip count and yields a 60 per cent reduction in PCB area compared to alternative devices, adds the company.

The MxFE platform meets the needs of other wide-bandwidth applications in 5G test and measurement equipment, broadband cable video streaming, multi-antenna phased array radar systems and low-earth-orbit satellite networks, confirms Analog Devices.

The AD9081 will be available as either a quad 12-bit, 4Gsamples per second and quad 16-bit 12Gsamples per second ADC in 324-BGA thermally enhanced packages. Sampling will begin in September, with full production scheduled for March 2020.

The AD9082 will be available as a dual 12-bit, 4Gsamples per second and quad 16-bit 12Gsamples per second ADC in the same package. Sampling will begin in September with full production scheduled for December 2019.

Smart mobility: Ukrainian city of Vinnitsa selects CIPURSE™ for transit ticketing

Mon, Jun 10, 2019

The city of Vinnitsa, Ukraine, is implementing a new, state-of-the art system for automated fare collection based on the CIPURSE™ open security standard. Infineon Technologies AG has been selected as sole supplier of the security chips to be embedded into 200,000 transportation cards for the city’s trams and busses. The cards will be issued from summer 2019 onwards.

The project is led by the municipal company Vinnitsa Card Service. Infineon is providing the CIPURSE security chips to be embedded into the cards. The hardware equipment for the terminals is being sourced from Mikroelektronika from the Czech Republic while Symbol Systems from Ukraine is responsible for software integration.

In a next step, the city of Vinnitsa will introduce social cards which combine transport ticketing with payment functionality. As part of the Ukrainian government’s roadmap towards a digital economy and society, similar projects have already been implemented in Ukraine. Local banks in the city of Zhitomir, for example, are issuing multi-application cards with CIPURSE-based security chips from Infineon.

Seamless and convenient solutions for public transportation

Population growth and continued urbanization are placing a growing strain on the environment. Public transportation is one of the key livability factors in a modern, smart city, extending beyond the obvious bus and train options to include services such as car-sharing and bike rentals. At the UITP Global Public Transport Summit in Stockholm, 9-12 June 2019, Infineon will be exhibiting transit ticketing solutions for seamless and convenient mobility

CIPURSE is an internationally supported, non-proprietary security standard for transport ticketing and access solutions. The specifications are managed by the OSPT Alliance. The truly open standard is highly flexible, supporting cards and tickets while also providing guidance for multi-purpose solutions. It is also supported in smartphones and therefore offers a convenient alternative to contactless tickets. Furthermore, providing future-proof security architectures based on Advanced Encryption Standard (AES) 128-bit key length, CIPURSE eliminates the fraud problems that tend to compromise existing proprietary systems.

Siemens integrates the u-blox ZED-F9K module into its V2X test fleet

Mon, Jun 10, 2019

The ZED-F9K turnkey solution minimizes the effort required to achieve decimeter-level positioning accuracy in automotive applications.

Thalwil, Switzerland – June 7, 2019 – u-blox (SIX:UBXN), a global provider of leading positioning and wireless communication technologies for the automotive, industrial, and consumer markets, is announcing that Siemens has integrated the u‑blox ZED-F9K (https://www.u-blox.com/en/product/zed-f9k-module) high precision dead reckoning module into its Toyota Prius V2X (vehicle-to-everything) test fleet. Siemens carried out live demonstrations of the technology at the ITS European Congress 2019 (https://2019.itsineurope.com/) in Eindhoven, the Netherlands.

As the only available source of absolute position, satellite-based positioning plays a crucial role in advanced driver automation systems and driverless vehicles. The same is true in V2X communication, in which vehicles continuously share their location and other information with other traffic participants – cars and pedestrians – as well as surrounding infrastructure, improving road safety and reducing traffic congestion.

V2X test vehicles typically determine their position using high-end, expensive GNSS (Global Navigation Satellite Systems) receivers. While these provide highly accurate position information, they fail to realistically represent the hardware that will be deployed in vehicles produced for the mass market. By opting to use the ZED-F9K turnkey solution for high precision dead reckoning, Siemens was able to align the performance of their test fleet with real world conditions while also reducing the cost and the engineering effort required to develop their vehicles.

“We’ve had a very positive experience with u-blox’s ZED-F9K high precision dead reckoning solution. The product delivered strongly from the initial design-in to the data and performance in our first tests,” says Igor Passchier, Engineering fellow, Connected and Automated Driving at Siemens PLM Software. “It underscores the reputation of u‑blox as a trusted innovator in GNSS technology.”

“Our collaboration with Siemens shows the extent to which the ZED-F9K turnkey solution saves OEMs time, cost, and engineering effort while providing decimeter-level positioning performance,” says Alex Ngi, Product Strategy for Dead Reckoning, Product Center Positioning, u-blox. “For us, it has also been a welcome opportunity to contribute to solving the challenges in the autonomous driving ecosystem.”
