November 2011 [Computer-Aided Engineering] CAE: Do Designers Trust Their Tools? Electronic-design-automation (EDA) tools are used for a variety of simulation and modeling tasks—from developing matching circuits for amplifiers through complete system simulation. October 2011 [Communications] New Tacks Are Taken To Roll Out 4G Infrastructure Fourth-generation (4G) cellular service has begun to roll out in earnest. September 2011 [Communications] Advanced Radios Strengthen Battlefield Communications Battlefield radios are essential tools for tactical communications, but many older radios are simply wearing out. August 2011 [Communications] Shrinking Cells Impact Base-Station Design Cellular Communications continues to experience a worldwide growth trajectory. Consequently, the need for base stations also continues to grow. According to Strategy Analytics, Inc., traditional macro and micro-cell base-station deployment will peak at slightly over 1 million base stations per year in 2012 before falling to slightly less than 1 million in 2014. However, the company sees explosive growth for... September 2010 [Components] Components Shrink, But Handle More Power High-power designs continue to be developed for both military and commercial applications. As original equipment manufacturers (OEMs) strive to miniaturize the footprint of the final design, the components designed to handle high power levels in those systems must also shrink. Some components can handle higher power levels due to material advances, better thermal management, clever circuit layouts, or a combination of these factors. As engineers... August 2010 [Components] Shrinking Sources Aim For Lower Noise esigners of oscillators and synthesizers need creative ways to achieve low phase noise in smaller packages in order to serve shrinking systems. To accomplish this, some manufacturers are using advanced materials and circuit techniques, as well as the latest software design tools, which can allow for extremely accurate simulations and speed time to market. Once a prototype is in hand, designers need to leverage the most robust methods and... |
