News From Washington Raytheon Delivers First Production Evolved SEASPARROW to US Navy Raytheon Co. delivered the first production Evolved SEASPARROW Missile (ESSM) to the US Navy, defining the future of ship defense. "ESSM provides improved ship self-defense capabilities against faster, lower, smaller and more maneuverable anti-ship missile threats as...

International Report BAE Systems C41SR Delivers First Skynet 5 Terminals UK contractor BAE Systems Command, Control, Communications, Computing, Intelligence, Surveillance and Reconnaissance (C4ISR) has delivered the first batch of six Talon satellite communications terminals to Paradigm Secure Communications for eventual use in the UK's Skynet 5 military communications satellite...

The Commercial Market Bluetooth to Ramp Up in Market Outside of Mobile Handsets While mobile handsets are expected to account for approximately two-thirds of the Bluetooth devices that will ship in 2002, and cordless headsets will also be a growing category, Allied Business Intelligence's (ABI) new Bluetooth report notes...

Wireless Communications - Principles and Practice, Second Edition Theodore S. Rappaport Prentice Hall PTR 707 pages; $92 ISBN: 0-13-042232-0 The second edition of this book has been written to initiate the newcomer to wireless personal communications, one of the fastest growing fields in the engineering world. Technical concepts which...

In today's fast paced semiconductor industry making accurate and reliable measurements at microwave frequencies is critical to successful product development operations. Microwave measurements enable engineers to characterize both the linear and nonlinear behavior of devices, providing critical performance information. Precise probe contact is a necessity to obtain accurate test...

A new substrate technology has been developed that addresses the dense component placement, high heat dissipation, harsh environments and high frequencies associated with high performance devices such as microwave amplifiers for base stations, broadband amplifiers designed into multi-media networks, and high power microwave power combiners with on-board terminations. The...

Atmospheric propagation attenuation is known to be higher in the 2.1 GHz band than in the cellular band. Thus, to overcome this performance disadvantage and to maximize cell coverage and capacity, Unity Wireless System's first feedforward multi-carrier linear power amplifier (MCLPA) product has been designed with a high 60...

Due to the fast growing demand for broadband wireless communications, the operating frequency is moving toward the 5 GHz U-NII band. With a maximum data rate of 54 Mbps, the IEEE 802.11a wireless LAN (WLAN) standard specifies a 300 MHz allocation of spectrum in the 5 GHz range that...

There are many ways of characterizing W-CDMA transmitter performance. However, the Third Generation Partnership Project (3GPP) specifications require two measurements to verify the in-channel modulation quality of W-CDMA transmitters - error vector magnitude (EVM) and peak code domain power (peak CDE). This article explores the purpose behind these key...
