March 01, 2004 - In This Issue [Cover Story] DUC Eclipses Competitive Offerings The cellular-infrastructure market continues to face its own set of challenges. Consider, for example, that the single most expensive component on a base station is the multi-carrier power amplifier (MCPA). Depending on the MCPA architecture and... — Cheryl Ajluni [Special Report] Looking For Ethernet Power? Find The Outlet, Nevermore Designers and customers alike are just beginning to appreciate the far-reaching effects of Power-over-Ethernet (PoE) technology. The products that meet the IEEE 802.3af PoE standard may revolutionize the installation of any device that's based on the... — John Blyler [Design Application] Test Sets Refine Handset Entertainment Wireless entertainment may soon lead to an upswing in the telecommunications market. In large part, its commercial success will depend upon the quality and usability of new mobile terminals. To run increasingly sophisticated games and other... — Jan Schiefer 3G-324M Helps 3G Live Up To Its Potential Broadband wireless is now a reality. Towers are converting to 3G throughout Europe and Asia. 3G-enabled phones are flying off the shelf and service providers are making a substantial commitment to the new format. At the same time, consumers are... — Eli Orr [Product Features] RFIC Test System Meets Wireless Needs For one of the hottest growth areas in the semiconductor market, look to radio-frequency integrated circuits (RFICs). These ICs are an essential part of any wireless device—be it a cell phone, laptop, or multimedia product. To ensure that they... — John Blyler High-Level Abstraction Comes Into Tool's Grasp Despite the economic downturn of the last two years, the electronic-system-level (ESL) design and verification markets continue to evolve. This fact proves the importance of system-level development software for the electronic-design-automation (EDA)... — John Blyler [New Products] Low-Ohmic Switches Deliver Audio Fidelity When dealing with audio applications, it's vital that the signal quality be protected. In space-constrained mobile applications, this obligation becomes even harder to fulfill. To help designers conquer these audio demons, three low-ohmic analog... — Nancy Friedrich Isolator Shrinks Down To Fit Digital Mobile Phones Varying and evolving standards make it hard for components to attain widespread implementation. As a result, components may choose to broaden their appeal. For example, Murata's 2-GHz-band isolator for the digital-mobile-phone market is significantly... — Nancy Friedrich Spectrum Analyzer Endures Harsh Conditions To successfully install, maintain, and troubleshoot wireless systems, technicians must quickly find, identify, and solve problems. Because this work takes place in the field, the technicians require both performance and ruggedness. Anritsu claims to... — Nancy Friedrich WLAN Front-End Modules Support 802.11 Blends The companies at the forefront of the wireless-LAN (WLAN) arena have been furiously pushing their technologies to the next level. Skyworks Solutions, for example, recently introduced a family of fully integrated 802.11 wireless-LAN modules. The goal... — Nancy Friedrich Miniaturized Oscillators Enhance WLAN Equipment For Wi-Fi chip sets to guarantee reliable frequency synthesis, they need stability to be maintained over all operating conditions. Impressively, SaRonix has managed this feat in its miniaturized crystal clock oscillators. Designed for... — Nancy Friedrich Bluetooth Solution Pushes Cell Phones To Market It seems that cellular-phone manufacturers simply cannot afford the time, space, battery power, and costs involved in adding Bluetooth to their designs. To conquer these obstacles, Silicon Wave and RF Micro Devices have released the SiW3500... — Nancy Friedrich [Column] Letters To The Editor DON'T PUT A SPIN ON HACKING I read your article in the November/December issue of Wireless Systems Design ("Balance Hacker Crime And Punishment," p. 15). You are way out on a limb here, dude. Hackers appear to... — Staff Speech Recognition Comes Of Age Speech recognition is a re-emerging technology. It survived the word-spotting '70s, the template-matching '80s, the trainable but unreliable cell-phone voice tags, and the Hidden Markov Model-based dictation programs of the '90s. Yet it only found a... — Jordan Cohen [News] Integrated Platform Speeds Verification Design teams must spend a lot of time and resources verifying their chip or system designs. This added pressure is fueling the search for true electronic-system-level (ESL) verification. So far, electronic-design-automation (EDA) companies are taking... — Nancy Friedrich Take The Right Technical Risks There is no shortage of books and other publications focusing on traditional risk management. But few publications address the peculiar aspects of innovation and design in the realization of high-tech products. One exception is Taking Technical... — John Blyler Functional-Verification Heavyweight Raises Scalability The electronic-design-automation (EDA) industry seeks to provide a crystal ball of sorts. Using EDA tools, designers and architects can predict many aspects of a chip's performance. When it comes to functional verification, however, the answers get... — Nancy Friedrich Short Clips Sony Corp. of Japan certified that Catalyst Semiconductor's (www.catalyst-semiconductor.com) environment management system meets the requirements of the Sony Green Partner Program. That program encourages suppliers to introduce Green Partner... — Nancy Friedrich Projecting ROI For A New Design Technology Can Save Time-To-Market And Money For today's engineering manager, one of the toughest challenges is predicting the return on investment (ROI) from implementing a new technology or design flow. To be successful in this forecast, one must understand the current cost structure; focus on... — Luis Aldaz [Editor's Note] Will Data Reign As The Next Big Thing? There's no denying the fact that momentum is growing in the wireless industry. But what's driving that trend? In my opinion, it all boils down to one thing—data! As far as I'm concerned, data is the next big thing in both the wireless industry... — Cheryl Ajluni [Around the World] Women And Wireless: How To Get Them Together The obvious boons of portability, ease of connectivity, and information-transfer speed make wireless a clear winner over carting around the old blue LAN or dial-up cables and an antiquated laptop. But when you ask people what wireless entails, most... — Joanne Jacobs Snapshots Atsana Semiconductor Corp. (www.atsana.com) raised $10 million in equity financing. The new round includes investments from Siemens Mobile Acceleration (Munich), GrowthWorks WV Funds (Toronto), Covington Capital Corp. (Toronto), Greenstone... — Nancy Friedrich [On The Wireless Front] On The Wireless Front Santa Clara, California National Semiconductor Corp. now offers a high-performance CMOS analog-to-digital converter (ADC). This ADC requires 75% less power than most comparable products on the market. The... — Cheryl Ajluni |
