The ‘electronics industry’ is diverse, wide ranging and all encompassing. Electronics is at the forefront of innovation and the basis for the latest technologies that impact and shape everyday lives across the globe, be it the cars we drive, Smart Grids monitoring our energy resources, medical equipment in surgeries or the communications that keep us in touch.
Every two years the evolution of electronics is demonstrated at electronica, the International Trade Fair for Electronic Components, Systems and Applications. When the 25th electronica at the Messe München, Germany, closed on 16 November more than 72,000 visitors had passed through the doors. A total of 2,669 exhibitors from 49 countries presented the future of electronics and showcased application-oriented solutions.
More than 72,000 trade visitors from 78 countries attended the Fair. Besides Germany, the countries with the largest contingent of visitors were Italy, Austria, Great Britain and Northern Ireland, Switzerland, France, the Russian Federation and the USA, in that order. The number of visitors from Canada, the Russian Federation, Turkey, the USA, the Czech Republic, Austria and Asia saw a significant increase.
Such numbers are encouraging, especially in the light of the economic downturn and there is no doubt that although the electronics industry is robust it has not been immune to the impact of the crisis and has had to adapt to the prevalent market conditions. However, at electronica 2012 the mood was generally upbeat with the industry looking forward to 2013 with cautious optimism.
That optimism was confirmed by Christoph Stoppok, Managing Director of the Electronic Components and Systems Association and the PCB and Electronic Systems Association in the ZVEI (German Electrical and Electronic Manufacturers' Association) who said in a statement: “After a minor slump, we expect the world market for electronic components to grow by some four percent to $480 billion. Forecasts also call for an increase in sales in the global semiconductor industry.”
The products on show covered the entire spectrum of technologies, products and solutions; from semiconductors, sensors, measuring 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. Besides Germany, the countries with the largest numbers of exhibitors were China, Taiwan, the USA, Great Britain, Italy, Hong Kong, France, Switzerland and Japan, in that order.
With the electronics industry being so wide and diverse, not all on show at electronica 2012 was 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 an idea 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.
Analog Devices Inc. (ADI) took a novel approach when teaming up with Wasatch Photonics Inc. to stage a Name That Beer demonstration using the Wasatch Photonics Stroker 785L Raman Spectrometer. Incorporating ADI’s A/D converter technology, the compact Raman laser spectrometer demonstrated how it could distinguish between 10 brands of German beer by reading the signature spectrum of each.
ADI also announced three new additions to its portfolio. The company unveiled what it claims to be the industry’s smallest isolated DC-DC converters, which use its proprietary isoPower® isolated DC-to-DC converter technology to deliver 150 mW of output power while using the minimum of board space. Secondly, a new FPGA mezzanine card (FMC) incorporates JEDEC JESD204B SerDes (serialiser/de-serialiser) technology to allow digital and analogue designers to simplify high-speed data converter-to-FPGA connectivity. Finally, ADI introduced a new 16-bit, 1-MSPS ADAS3022 data acquisition IC that is effective for power-line monitors, process and motor control, patient monitoring, and other industrial and instrumentation systems that operate within the ±10 V industrial range.

Agilent Technologies introduced a high-precision PXIe frequency reference – the Agilent M9300A, which generates clean 10 MHz and 100 MHz signals for high-performance RF systems. The company designed the M9300A for applications that require a low phase noise, 100 MHz local oscillator, such as those in a wide variety of wireless and aerospace/defence test systems.
The new frequency reference is packaged into a one-slot PXIe module and uses a fractional-N design which minimizes phase noise and spurs. The M9300A features the ability to lock to an external reference from 1 to 110 MHz and provide flexibility with multiple outputs. Engineers can use the M9300A PXIe frequency reference with the Agilent M9380A CW Source or the M9381A PXIe vector signal generator to achieve its high-performance specifications, including greater speed. As the M9300A conforms to the PXI standard, it can be used in any PXI system where PXIe or PXI-H slots are available, regardless of the vendor.

The transmitter also features low phase noise, coupled with low power consumption and a wide tuning range.
Infineon Technologies released the next generation of thin wafer Insulated Gate Bipolar Transistor (IGBT) by introducing TRENCHSTOP™ 5. With an increased breakthrough voltage of 650 V the new technology provides a higher safety margin for designs. Target topologies are boost PFC (AC/DC) stage and high voltage DC/DC topologies commonly found in applications such as Photovoltaic Inverters, Uninterruptible Power Supplies (UPS) and Inverterised Welding Machines.
The TRENCHSTOP™ 5 provides the basis for two product families. The HighSpeed 5 (H5) is a soft high speed IGBT designed for ease of use and the plug and play replacement of existing IGBTs, since it requires minimum design-in effort. The HighSpeed 5 FAST (F5) is claimed to be the most efficient IGBT; for example, more than 98 percent system efficiency has been observed in application measurements on a photovoltaic inverter using a ‘H4 bridge’ topology.
IQD extended the performance of the IQOV-90 series high stability low phase noise OCXOs to encompass the full standard industrial temperature range of -40 to 85°C. The new design is available in frequencies from 10 to 40 MHz and with supply voltages of 12 V, 5.0 V or 3.3 V. Both sinewave and HCMOS outputs can be specified along with a frequency adjustment option and additionally, a reference voltage output where required. As a further option, an oven alarm output is available which indicates when the OCXO is at a stable working condition after warm-up.
Housed in a 25.4 x 22.0 mm package with a height of 12.3 mm, the new design satisfies applications where space and height is limited. Based on a FR4-PCB with a metal lid and delivered in package quantities of 75 pcs per reel the IQOV-95 is suitable for fully automatic SMD production. Its applications include base stations, repeater stations, instrumentation, medical and measurement equipment.
