Ultra wideband (UWB) has received a lot of press recently for personal area networking and connectivity. But is that the whole story? Not at all: there are a number of other uses for the fledgling format, which have nothing to do with the sub 5 to 10 meter space....

In spite of what some market analysts might believe, In-Stat/MDR reports that the application-specific IC (ASIC) market is alive and well and will continue to prosper in the future, albeit at a lower pace than history would have dictated. The high tech market research firm finds that product differentiation...

Modern Receiver Front-Ends: Systems, Circuits and Integration Joy Laskar, Balak Matinpour and Sudipto Chakraborty Wiley-Interscience 234 pages; $79.95 ISBN: 0-471-22591-6 The main focus of this book is the integration of, and interaction among, various building blocks for, and the development and characterization of, receiver subsystems for wireless applications. Such...

Selection Guide This 20-page digital design and debug solutions selection guide includes product comparison tables for oscilloscopes, logic analyzers, pulse pattern generators, bit error ratio testers and probing solutions for easy evaluation and selection. The guide provides quick access to product information, expert and comprehensive product support, and technical...

Raytheon Co. has received a $369 M System Development and Demonstration (SDD) contract for Phase II of the US Air Force’s Multi-platform Radar Technology Insertion Program (MP-RTIP). Since December 2000, Raytheon and Northrop Grumman have been teamed for the design, development and production of the Air Force’s next generation...

Creating the complete transmission path of a satellite in training, development, troubleshooting, or system set-up applications requires three components: two earth terminals and a spacecraft. While terminals are generally accessible, satellite accessibility is more problematic, requiring costly leased time on an orbiting spacecraft and offering no control flexibility. Often,...

When implementing the evolution of TDMA wireless networks to GSM/GPRS and then W-CDMA, service providers “overlay” GSM/GPRS by integrating a new base transceiver station (BTS) with the existing TDMA BTS. Carrier signals from the new BTS are fed through the TDMA transmit chain to the existing antennas, and receiver...

For mobile phones, WLAN and other wireless applications, RF engineers need to perform sophisticated IC designs under strict time-to-market constraints. To make this possible, with as few prototyping cycles as possible, RFIC design tools must incorporate efficient methods for analyzing circuit behavior, accurate semiconductor models and flexible system modeling...

Microwave engineers have been forced to verify the validity of their high frequency design interconnects either by manual inspection or by using layout versus schematic tools designed for analog/digital design. Such tools, which are well established for low frequency design, tend to be less than optimal for high frequency...

The state-of-the-art indoor wireless systems operating at microwave frequencies (approximately 2.45 and 5.5 GHz) have been standardized in conformance with different multiplexing schemes and modulation techniques. The underlying design considerations 1,2 aim at realizing robust operation of several interconnected and coexisting hosts 3 across RF links. These links are...
