News From Washington Lockheed Martin Receives $260 M Contract for PAC-3 Missile SegmentLockheed Martin has received a $260 M not-to-exceed contract for a Missile Segment Enhancement (MSE) to the battle-proven Patriot Advanced Capability-3 (PAC-3) Missile. The MSE provides performance enhancement to the missile that will counter evolving threat advancements....

International Report Alcatel to Deliver Afghanistan's New GSM Network The Telecom Development Company Afghanistan (TDCA) has signed a contract for the supply of a complete solution for GSM infrastructure and services, including the deployment of microwave radio and carrier-class transmission solutions. The system is already operational in Kabul under...

The Commercial Market UWB Technology Closer to Ratification In order to gain acceptance and grow, a technology needs to be standardized by the industry, enabling equipment and peripheral manufacturers to create, distribute and sell compliant products. According to ABI Research, ultra-wide band (UWB) wireless technology took a step closer...

Planar Antennas for Wireless Communications Kin-Lu Wong Wiley Interscience 301 pages; $89.95 ISBN: 0-471-26611-6 With the advent of cellular communication systems and wireless local area networks, planar antennas with low profile, such as microstrip and other printed antennas, have been receiving a lot of attention. Many researchers, including the...

A line of variable gain amplifiers (VGA) has been introduced for use in transmitter and receiver automatic gain control (AGC) circuits, and as variable gain blocks following low noise amplifier stages in high dynamic range receiver front ends. The new amplifiers integrate high performance amplifiers and attenuators within a...

Double-balanced mixers are used extensively in transmitters and receivers. For frequencies above 5 GHz the designs are normally realized using strip line and microstrip techniques. This is because distributed element baluns become smaller in size and more attractive for design as the frequency increases. Semiconductor-based mixers are the most...

Two broadband satellite networks are in the final stages of development and plan a service launch for North America in early 2004. Systems like these are expected to provide wideband, high speed communications for Internet and multimedia applications across North America and Europe for years to come. High power...

There is good news for those thinking about adding wireless communications to their industrial, scientific, or medical (ISM) application. A variety of low power, low cost radio ASSPs are available that can provide wireless features specifically for ISM applications. Fortunately, you do not need to be a communications specialist...

Determining cross-modulation interference is an important factor in the design of a code division multiple access (CDMA) mobile transceiver. The cross-modulation interference level directly affects the performance of the receiver's ability to overcome the spurious interferences, such as what the IS-98 1 calls single tone desensitization. A few papers...
