Figure 2 shows the Linduino One board connected to an LTC2607 dual 16-bi t digital-to-analogue (DAC) demo board, one of more than 300 USB-based data acquisition cards that connect to individual daughter cards for specific Linear Technology products.

The stability of the defence business remains attractive and according to SIPRI, [1] global military spending has increased annually by 2.5% (CAGR) over the past two decades. The declines in military spending in the US and Europ e since 2009 have probably now stabilised and are expected to resume steady upward momentum going forward. In response, the defence industry has regrouped and consolidate aerospace industry and, in


particular civil d, while the


aircraft, has continued to expand, driven by ever increasing passenger numbers. There is also a significantmove to


commercialise space with the development of large low cost constellations of communications satellite s.


Across the aerospace and defence sector, the business has always been cyclic in nature, influenced by large programmes. But today, development cycles are much shorter and the focus on value for money has intensified with cost-reduction redesigns becoming

increasingly common. At the same time, fewer design resources are available, following rationalisation of organisations, driven by cost cutting measures as the industry struggles to becomemore efficient .

Despite these pressures, the appetite for new technology has not diminished and improvements in SWaP (size, weight and power) are realised by using more


complex integrated circuits and software. Fewer design resources andmore complex products have increased the importance of easily accessible online sources of information. Linear Technology, for

countermeasures, unmanned vehicles and soldier-carried equipment. Low quiescent power consumption and high efficiency voltage conversion is one common thread tomaximise run time for battery-based equipment. The company has developed its Silent Switcher architecture, implemented in products such as its LT8614, shown in Figure 1. This 42V, 4A synchronous step-down Silent Switche r reduces EMI/EMC emissions bymore than 20dB compared to standard switchers, resulting in lower systemnoise and improved sensitivity or resolution.


In the future, the company expects to see spending on electronics continue to increase as a percentage of total equipment, driven by complex data networks with many more sensors and more focus on big data analytics. There may be more emphasis on flexibility i n systems to deal with the wider range of threats, better-integrated fighting forces, and command and control


systems. Independent energy generation for fighting forces, more use of green energy sources and hybrid-electric powered systems will also become more important, and all of these imply more complex electronics.


In summary, the company views excellent design support and tools, innovative products and long-ter m, continued support of products over decades of production as essential to aerospace and defence customers.
