EDGE Modulation — How Linearization Improves Amplifier Performance
Oct 1, 2002
By T. J. Fergus Historically, the global system for mobile Communications was intended to make power amplifier design simpler. With the introduction of high order modulation schemes for 2.5 and 3G, the design challenges presented to the PA have increased significantly. This article describes the design and implementation of a polar loop to improve the efficiency of a gallium-arsenide field effect transistor (GaAs FET) power operating at 1.91 GHz....

Mixed Signal Spearheading the Need for Improved Design Methodologies
Oct 1, 2002
By Henry Y. Chang Mixed-signal ICs are ushering in a new era of amazing possibilities for systems-on-a-chip (SoC) design. Nowadays it's not uncommon to incorporate hundreds of thousands or even millions of gates onto a single chip, including a sizable peripheral analog circuitry. And because mixed-signal devices feature increasingly complex analog components, it's spearheading the need for improved design methodologies....

Designing MIMO systems for Reliable Coverage in Non-LOS Wireless Links
Oct 1, 2002
By Victor Shtrom, Ph.D. Jose Tellado, Ph.D. and Professor A. Paulraj Providing wireline reliability in non-line-of-sight wireless environments presents a particular set of challenges. Difficulties lie in the fact that the received signal power at a location in space is not constant. This truism of wireless communications underscores one of the wireless industry's greatest challenges in enabling broadband wireless connectivity. Recently, multiple antenna technologies have demonstrated notable success in defeating early systems' LOS limitations....

Indoor propagation issues for wireless LANs
Sep 1, 2002
By Dan Dobkin Wireless local area networks (WLANs) are rapidly gaining popularity. These networks are primarily targeted for indoor use, and most often use the unlicensed bands at 2.4 to 2.5 GHz or 5.15 to 5.85 GHz. It is often said that the higher-frequency unlicensed national information infrastructure band at 5.15 to 5.85 GHz will be intrinsically limited to shorter ranges than the industrial/scientific/medical band due to higher path loss. The purpose of this investigation was to examine that claim....

Design Chebychev bandpass filters efficiently
Sep 1, 2002
By B. Mayer, PhD, M. H. Vogel, PhD Designing filters is not an easy talk, despite the fact that the technology involved is mature and understood. Modern software tools are available that provide the circuits in terms of lumped electrical components, but designing the actual 3D microwave structure can take weeks. This article shows how a circuit simulator and a 3D field solver can work together to reduce the design time from weeks to days....
