EuMW 2017, Nuremberg – Moving with the Times

October 19, 2017

Final numbers are yet to be confirmed but pre-registration figures, evidence of initial attendance, the interest in the conference sessions, short courses and workshops and activity on the show floor bode well for European Microwave Week that took place at the Nürnberg Convention Center from 8 to 13 October being another record breaker. Nuremberg may be steeped in history and while many of those attending EuMW 2017 took the opportunity to step back in time to enjoy the medieval spectacle of the city’s Old Town it was the activity of the present and the promise of the future for the RF and microwave industry that was of key interest.

DroneSpecific focus was on how the latest technology could be delivered – literally – as the increased interest in the development and application of drones in the RF and microwave sector was palpable. Their ability to access difficult or even impossible sites in crowded spaces or at a distance with flexibility and relatively little cost is opening up new possibilities for mapping, testing etc. For instance a lightweight spectrum analyzer suspended from a drone can perform mmWave spectrum monitoring in 3D or be flown into a satellite for precise measurement.

ADASAnd, of course, with Germany at the forefront of automotive development the vital role that RF and microwave technology is playing in the industry’s advancement was demonstrated to a greater extent than ever before at EuMW 2017, where the focus was on Advanced Driver Assistance Systems (ADAS) on its way to Highly Automated Driving (HAD) in the Future, with four workshops and three sessions within EuRAD dealing with the subject.

Also, within the entrance hall of the Nürnberg Messe at NCC OST there was a special exhibition of technology demonstrators and test cars from Mercedes-Benz, Bosch, Hella, and Valeo. Test cars equipped with radar were available outside the Messe for test drives in the Nuremberg urban environment, while an Intelligent Drive Simulator in the entrance hall offered the opportunity for a hands-on operating experience. And, last but not least – in front of exhibition Hall 7A automated parking trials could be observed.

Indeed, the prime aim of European Microwave Week is to put the RF and microwave community in the driving seat and on the road to success by providing cutting edge conference content, showcase the latest innovations on the show floor with face-to face contact and hands-on demonstrations, together with numerous networking opportunities.

Regarding the conferences, a specific aim this year was to capitalize on the strength of international, national and local industry and academia with the introduction of the new Session Keynotes format, designed to boost industrial participation and intensify the interaction between industry and academia. For this, internationally recognized experts from industry open selected sessions with presentations on challenges and state-of-the-art achievements in their field, which was well received.

DSSThe Defence, Security & Space Forum continued to go where no Forum has gone before as it ventured into: The Internet of Space – Technologies and Applications, that focused on how a new class of satellite communication can be developed utilizing state-of-the-art microwave and millimeter wave technologies.

EuMW promotes inclusivity, epitomized by the Women in Microwave Engineering event, and planning for the future with events specifically tailored to the younger generation, including the very successful Student Challenge, the Student Design Competition, the European Microwave Doctoral School designed to address the needs of PhD students and The Career Platform aimed at putting prospective directly employees in touch with participating companies.

For young and old, established or new to the industry, an integral and vital constituent of EuMW is the European Microwave Exhibition, which, this year, took up 8000 square meters of gross space and attracted 349 exhibiting companies. The exhibition hall was not only a focal point for innovation but also a platform for interaction. Offering an industry lead focus the European Microwave Week Microwave Application Seminars (MicroApps) took place in the MicroApps Auditorium for the entire three days of the exhibition, providing an informative insight into the latest technology and some lively debate during panel sessions. Also, for the first time, Interactive Sessions saw papers displayed on active presentation screens instead of the posters used in previous years.

ReceptionThe opportunity interact on a personal and professional level was provided by the Keysight Technologies sponsored Welcome Reception on the Tuesday evening, which is designed to be convivial and encourage networking between delegates and industry. This year the atmosphere was added to with the cutting and consumption of a birthday cake and entertainment from mutli-colored light wielding performers!

The exhibition was the place to come face-to-face with the latest technology, establish and re-engage contacts and do business. It is also offers a platform for innovation that leading manufacturers often choose to launch new products and float future concepts, with this year being no exception. Below is a selection of the new and innovative products on show at EuMW 2017.

AMCAD Engineering launched VISION, an advanced RF circuit and system modeling solution for accurate RF & MMW system design. Building RF systems which are designed to operate with wideband modulated signals, like 5G, or with a large number of circuits, like active antennas, is challenging. Looking at the simulation accuracy, the bottleneck is always the model quality used by the simulators, because the different memory effects that take place into the different circuits are not always modeled with a comprehensive methodology. VISION enables measurement setup for model extraction and validation plus concatenating different circuit models to create a macro model using a schematic editor. It provides efficient system simulations that do not need circuit level co-simulations and can account for both low and high frequency memory effects. It will be interesting to see how this new system design tool catches on since it seems very powerful and easy to use.

Ampleon displayed its latest range of innovative RF power targeting the mobile broadband, broadcast, ISM, aerospace and defense and RF energy segments. Highlights included: new Doherty amplifiers for UHF DTV broadcast, high efficiency S-Band radar pallets and transistors – LDMOS for C-Band, next generation high power broadband GaN, what is claimed to be the smallest 2.5 GHz, 915 MHz and 433 MHz modules for RF energy and Thor, the first modular power amplifier reference design for RF energy applications based on Ampleon pallets.

ADIAnalog Devices introduced a 9 kHz to 7 GHz directional bridge and dual RMS RF power detector that can simultaneously measure forward and reverse RMS power levels in a signal path along with return loss. The ADL5920 detector integrates a directional bridge-based coupler that results in an industry leading level of integration and bandwidth. For space-critical applications, it integrates the coupling or sensing function with the detection function and provides an output that can drive a precision ADC directly. For wideband operation or for frequency variants, the detector eliminates the need to choose a different directional coupler for each frequency.

ADI also announced a 14-bit, 2.6 GSPS dual A/D converter which enables IF/RF sampling with superior speed and linearity. The AD9689 A/D converter features power dissipation of 1.55 W per channel, half the dissipation of comparable solutions in the market, thus further increasing suitability for many of its targeted design situations. ADI also introduced two related converters: the AD9695, a dual 14-bit 1300/625 MSPS device, and the AD9697, a single 14-bit, 1300-MSPS unit. Both are lower-power, pin-compatible upgrades for existing devices. All three A/D converters include JESD204B interfaces for efficient and highest-speed interconnection to FPGAs, and share the same register map, so they can be used across multiple platforms with minimal coding efforts.

AnritsuAnritsu Corporation showcased its latest spectrum analyzer/signal analyzers and vector network analyzers. Centre stage was the Spectrum Master™ MS2760A series of mmWave spectrum analyzers that deliver up to 110 GHz spectrum from an instrument that fits in the palm of the hand and can be used for applications such as 5G, E-Band, 802.11ad/WiGig, satellite communications, electronic warfare and automotive radar. Due to its light weight (300g) an application that was demonstrated at EuMW was drone based mmWave spectrum monitoring in 3D!

Another demonstration showed the analyze of 5G signals using the MS2850A signal analyzer with a maximum analysis bandwidth of 1 GHz by performing analysis of an 8-carrier simultaneously (100 MHz x 8 = 800 MHz total) signal output from the demonstration signal source. This demonstration generated an 8 x 100 MHz 5GTF waveform at 28 GHz and detailed resource block level analysis of the signals. This demonstration generated an 8 x 100 MHz 5GTF waveform at 28 GHz and detailed resource block level analysis of the signals.

The company also demonstrated several spectrum monitoring and signal analysis solutions including: using VISION and SpectraVision Software with a High-Speed Port Scanner, a live demonstration of TDOA geolocation with a testbed in Munich and demodulation of satellite communication signals with SpectraVision.

ANSYSANSYS discussed their new 3D components that are self contained HFSS models. It is extending the component concept from circuit/schematic to CAD/FEA. More complex geometries can be encapsulated in a compact design file, a 3D Component that can be easily reused and shared by users of HFSS. These 3D Components contain all the FEM simulation information associated with the parts of the components. In addition, the component creator can control what design parameters (e.g. dimensions, material properties) are accessible for control to the end user. In the HFSS UI 3D components can be dragged and dropped into a more complex 3D design or system without requiring creation of the entire 3D design from scratch in CAD. So a user assembles a complex 3D system from more basic components as schematics are assembled from circuit components. They have enabled 3D Component Encryption with Hidden Content where the 3D Component creator can elect to hide certain parts of their design (e.g. geometry, materials, boundary conditions) while only exposing enough geometric information to allow an end user to properly place the component(s) into their overall design. However, the HFSS simulation is fully aware of all the details in the component for a full and rigorous HFSS 3D analysis to capture all electromagnetic couplings between the component(s) and the design. The resulting solution is not a cascading of S-parameter models but a true three dimensional HFSS analysis.

API Technologies announced a collaboration with Analog Devices (ADI) for the production of custom, high reliability modules and assemblies for aerospace and defense (A&D) programs in the European market. API will design and manufacture the custom products in the U.K., combining ADI’s digital signal processing and RF products with API’s design and manufacturing capabilities. The two companies will jointly market their collaboration to European A&D customers. API also highlighted a new product line of optoelectronic transceivers that replace traditional electrical cables with fiber-optic connections. The OPTO-Fire™ high speed fiber-optic transceivers reduce system weight, particularly important in airborne applications, improve security, by eliminating the electromagnetic radiation from copper cabling, and improves data transfer. The single channel fiber core is capable of data transfer rates from 20 Mbps to 12.5 Gbps. The OPTO-Fire transceivers are designed for harsh environments, including airborne, naval and renewable energy.

ARAR was featuring their new “U-Series” amplifiers with CW outputs of  1. 2.5, 25 and 50 W over the frequency range of 10 kHz to 1 GHz. For example, the Model 50U1000 is a solid-state, self-contained, air-cooled, broadband amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. When used with a sweep generator, it will provide a minimum of 50 watts of RF power. Included is a front panel gain control which permits the operator to conveniently set the desired output level. The 50U1000 is protected from RF input overdrive by an RF input leveling circuit which controls the RF input level to the RF amplifier first stage when the RF input level is increased above 0 dBm. The RF amplifier stages are protected from over-temperature by removing the DC voltage to them if an overtemperature condition occurs due to cooling blockage or fan failure. Also featured were the high power and extended bandwidth S-Series, pulsed series and hybrid modules.

Arralis announced the commercial release of the Corvus range of Level 4-5 Autonomous chips.

Gapwaves was a new company to me with an interesting technology. GAP waveguides is a unique packaging technology for mmWave and terahertz circuits and components that has advantages compared to existing transmission line and waveguide technology. The technology enables planar solutions with low losses, operating typically from 30 GHz to THz in applications such as antenna systems for Gigabit speed wireless communication and backhaul. The technology is based on an Artificial Magnetic Conductor that enables contactless propagation of electromagnetic waves, significantly reducing transmission losses. Antennas based on the GAP technology have more than 10 times lower losses than micro strip lines, more than 3 times lower losses than SIW, and approximately the same losses as rectangular waveguides. The GAP waveguide technology can create tightly integrated solutions, including planar antennas, filters, diplexers, and other active components. GAP antennas with multiple ports are suitable for beamforming applications and is working with several providers on 5G solutions so will be interesting to follow their progress.

Maury Microwave was showing off AM3000 PIV system, designed specifically for synchronized PIV/RF measurements and compact model extraction.  What is unique about this new hardware is the asynchronous recharge, which allows us to extend a typical 1 ms maximum pulse width to 200 seconds. These wider pulse widths allow unique investigations into trapping effects and allow engineers to model these trapping effects quite accurately. The second advantage is the new 18-bit ADC which allows for a lower the noise floor and turn what used to be low-current noise into clear IV curves. They also showed the MT2000 mixed-signal active load pull system and demonstrated a pre-5G signal with 120 MHz of wideband impedance control at 3 GHz and 240 MHz of impedance control at 6 GHz (second harmonic frequency). This is the only active load pull system capable of 240 MHz of impedance bandwidth control, and the only system suited for load pull of modulated signals. Lastly, they discussed the pre-release of IVCAD 3.7, with the addition of traditional load pull to our already implemented VNA-based load pull.  Adding traditional load pull to IVCAD enables engineers to build a single load pull system comprising of both modulated load pull and VNA-based active harmonic load pull.  They expect to release IVCAD 3.7 within 6 weeks.

Mician featured Version 8.1, the latest release of its µWave Wizard hybrid EM-design software design tool using the well-known fast and accurate Mode-Matching (MM) technique.
