New centres that offer UK-based businesses flexible and affordable access to cutting-edge scientific equipment and laboratory space for high-tech research and development work have opened at STFC Daresbury Laboratory, part of the Daresbury Science and Innovation Campus in Cheshire, UK. More than £3 M of cutting-edge equipment is available...

The economic downturn is likely to cause a slowdown in North American and European in-building wireless (IBW) deployments during 2009-10. ABI Research sees flat growth in those regions for ‘09-10; however, typical 20 to 25 percent annual growth is expected to return by 2013. Buoyed by constant high growth...

The recession contributed to 2008 having the slowest total global broadband customer premises equipment (CPE) market growth this decade of 2.4 percent (to 154M units), according to market research firm, In-Stat. 2009 will be even slower. However, cable gateways, wireless and VoIP routers, and wireless and VoIP DSL CPE...

Wi-Fi seems to be all-pervasive, and in the year 2011 alone, Wi-Fi chipset vendors will ship one billion units, according to market data just released by ABI Research. By the end of the following year a cumulative five billion such chipsets will have shipped since the firm began tracking...

The global economic meltdown slowed year-on-year GaAs industry growth from its previous forecast of 9 percent down to 6 percent in 2008. With the market projected to contract again 5 percent year-on-year in 2009, gains made in 2008 will be effectively wiped out and the GaAs industry is projected...

Industry News MI Technologies , a provider of advanced engineering, wireless, precision instrumentation and measurement systems, announced it has entered into an agreement to purchase the majority of the assets and have exclusive rights to all IAM System’s designs and products. Since its inception, IAM Systems has been a...

The last decade has been marked by rapid development in the avionics integrated systems that have important advantages: Fewer units, smaller size, less weight, lower power use, reduced cable count, extensive built-in test equipment (BITE) and integrated maintenance features. This article describes different aspects of RF design of the...

Modern wireless communication systems demand not only high efficient RF and microwave amplifiers, but wideband designs too. Switchmode power amplification classes can provide both benefits simultaneously, but theoretical knowledge must be combined with important practical considerations to get these advantages. There are important practical considerations that limit the theoretical...

This paper describes a concept of non-adaptive Digital Feed-forward Linearization. A feed-forward amplifier is a system designed to reduce the spectrum re-grows appearing due to the amplifier’s nonlinearity. There are several general techniques to reduce nonlinearity effects. They are divided into two major groups. One of them (called “predistortion”)...

Phase noise is the most important figure of merit of microwave oscillators. 1,2 Although a number of publications have addressed this phenomenon, it still remains one of the most challenging aspects in oscillator design. This article briefly summarizes the research and development effort in the area of low-noise signal...
