- Buyers Guide
The intervening two years between electronica 2008 and electronica 2010 has seen the economic downturn take grip. Individual nations, both established and emerging have had to take stock and, in many cases, stringent measures too. All major industries have felt the impact of the crisis and are having to adapt to the prevalent market conditions, while individual companies have generally had to take stock and address issues such as efficiency, organisation, investment, etc. The ability of an industry to grow through the research and development of new technology is key to future prosperity, so electronica 2010, which was held at the New Munich Trade Fair Centre from 9 to 12 November, was a significant barometer of how the ‘economic’ has impacted the ‘electronic’.
In fact, on the first day of the event an audience of 350 attended the CEO Round Table to hear the CEOs from four leading semiconductor manufacturers – Infineon Technologies, Freescale Semiconductor, STMicroelectronics and NXP Semiconductors – debate: “What have we learnt from the crisis?”
While recognising that, in the past, manufacturers had developed products that did not match customers’ requirements, the participants agreed that leading companies in the semiconductor industry had purposefully invested in R&D during the crisis in order to make sure that they emerged from it in better shape. Also, while welcoming an upturn, particularly in the last two months, they conceded that the scale of improvement had led to delivery bottlenecks at times and accepted that, in future, such bottlenecks can only be avoided through closer cooperation between manufacturers and customers in order to match requirements at an early stage.
While recognising and accepting the significance of the economic downturn, especially as the lessons learnt must form the basis of how to ensure development in the future, electronica 2010 focused on providing a platform for the electronics industry to showcase its current activity and look forward.
With over 70,000 trade visitors and 2,595 exhibitors from 45 countries, the Trade Fair emphasised its position as the international meeting-place for the electronics industry. electronica 2010 covered the entire spectrum of technologies, products and solutions, from semiconductors, sensors, measurement and testing, electronics design, passive components, power supply, PCBs and other non-mounted circuit carriers through to EMS.
Due to the strength of the automotive industry in the Munich area in particular, and Germany in general, together with the increasing use of electronics in automotive applications, this sector of the electronics market was well represented with 1,281 exhibitors presenting products and services related to automotive applications.
Electronic applications in medical technology were also to the fore with 1,156 exhibitors displaying innovations in medical electronics. Environmental issues were also highlighted as a total of 518 exhibitors presented electronic products for the management and monitoring of photovoltaic systems and the topic of renewable energies was prevalent throughout the trade fair. At the end of the show there was general agreement amongst exhibitors that companies can expect stable growth in the future and are banking on innovative future technologies.
Complementary to the Trade Fair were three associated conferences. This year the two-day electronica automotive conference was attended by 323 delegates from 23 countries. The first day included presentations about markets and strategies from leading executives in the semiconductor, supply and automotive industries. The second day covered topics ranging from charging infrastructure, high-voltage contactors and multi-channel 77 GHz radar solutions to the capabilities of components in electric drive systems.
The Wireless Congress 2010: Systems & Applications considered wireless applications as a driving force for research and development and was aimed at developers, system designers, technology decision-makers, project managers and wireless system authorities. It offered an insight into current applications, safety aspects, certification and qualification problems, test and measurement, standards and market opportunities.
Finally, CARTS Europe 2010, organized by the Electronic Components Association, aimed to provide component engineers and designers with the latest technical and market intelligence on capacitors, resistors and other passive components.
Four sector-specific forums – the automotive forum, the embedded forum, the electronica forum and the ZVEI forum (ZVEI standing for the German National Electrical and Electronic Manufacturers Association) – offered panels of experts and other specialists a platform to deliver company presentations and discussions and introduce new products and innovative systems. The automotive forum and embedded forum are self-explanatory and were sector specific, while the electronica forum and ZVEI forum concentrated on general technology topics and other applications such as MEMS, medical electronics, wireless, organic electronics, photovoltaics and renewable energies.
electronica 2010 covered the entire electronics spectrum, not all of which is pertinent to Microwave Journal readers. However, a number of manufacturers active in the RF and microwave sector targeted the show for new product introductions. To provide a flavour of the diversity and variety that the Trade Fair offered the following provides a cross-section of some of the new products showcased. It is impossible to mention them all here and apologies to any company not represented.
Taking centre stage for its worldwide debut for Aeroflex was the S-Series RF signal generator family. The range of instruments has been designed from the ground up to meet the expectations of today’s engineers for instant answers at the touch of a screen. Buttons, rotary controls, and deeply nested software menus have all been removed. A modular format, featuring the new Aerolock™ locking mechanism, allows additional RF instruments such as a second signal generator and combiner to be mechanically coupled externally by the user.
The first in the series is the Aeroflex SGA analogue RF signal generators that are currently available in two models: the SGA 3, which has an operating frequency range of 100 kHz to 3 GHz, and the SGA 6 covering 100 kHz to 6 GHz. A typical single sideband (SSB) phase noise specification of -135 dBc/Hz at 20 kHz offset from a 1 GHz carrier means that the SGA signal generator can easily measure receiver selectivity beyond 80 dB. Fast frequency settling times of 1 ms in conventional frequency selection mode, or 100 µs in list mode, make the instrument suitable for frequency hopping and semiconductor test applications, as well as ensuring maximum throughput in a production environment.
Maximum RF output power is +13 dBm, with a resolution of 0.01 dB, and a high power option is available to extend the maximum calibrated RF level to +20 dBm. Power level can be switched rapidly using an electronic attenuator, in less than 100 µs to within 0.1 dB of final value, and repeatability is better than 0.05 dB. A digital sweep of carrier frequency, RF level and modulation source is included, with single, continuous or externally triggered modes, as well as a list mode sweep facility.
In the future, the S-Series is planned to include digital signal generators for wireless-specific measurements including LTE, LTE-A and IEEE 802.11ac standards, and a range of signal analyzers.
