Northrop Grumman Corp. will help the US Air Force enhance the surveillance capabilities of aerial vehicles by embedding antennas in the primary load-bearing structures of composite aircraft wings. The new approach could lead to antennas as large as the surface area of a wing with enough sensitivity to simultaneously...

The contract to build what will be the world’s largest shared TETRA public safety network (in terms of geography) has been won by a consortium led by Saab and including Nokia and Swedia. The Swedish government has chosen the Nordic consortium to build a professional mobile radio network for...

A€20 M contract has been awarded to EADS Defence Electronics (DE) by US-based ViaSat Inc. to supply core electronics that will enhance the US armed forces’ network-enabled capabilities. The contract covers the delivery of 400 power amplifiers, which are core components of the US Multifunctional Information Distribution System (MIDS)....

Irish Broadband, a subsidiary of NTR plc, a developer of private infrastructure, has announced its intent to commercially deploy one of the first next generation, non-line-of-sight (NLOS) wide-area wireless broadband networks in the European Union at 3.5 GHz. The company is utilizing Navini Networks’ Ripwave™ product line. The rollout...

DiGi Telecommunications (DiGi) has selected Ericsson as a network infrastructure provider for its network upgrade to EDGE in the Klang Valley, which includes the capital city of Kuala Lumpur. The company will supply the necessary EDGE network infrastructure and equipment, including the upgrade of associated core network and supply...

According to ABI Research, the possibility of obtaining consensus on a single ultrawideband (UWB) standard for wireless personal area networks (WPAN) has disappeared. There are two standards on the table, one proposed by Motorola and a couple of others, and the other proposed by nearly all the remaining industry...

High Frequency Techniques: An Introduction to RF and Microwave Engineering Joseph F. White Wiley-Interscience 502 pages; $94.95 ISBN: 0-471-45591-1 This book is intended for the undergraduate or graduate student who wishes to pursue a career in radio frequency and microwave engineering. It presumes that the student has access to...

The US Army Aviation and Missile Command has awarded Raytheon Co. a $127 M contract for the US Army and US Marine Corps Surface Launched Advanced Medium Range Air-to-Air Missile (SLAMRAAM) System. Raytheon’s Integrated Defense Systems will lead Team SLAMRAAM to develop, fabricate, integrate and test the SLAMRAAM system....

Part I of this article 1 analyzed the driving circuits and methods for power amplifiers, using a low frequency approximation. This second part deals with the driving problem at high frequencies. Using a simple yet effective (for this purpose) active device model, the influence of the intrinsic feedback capacitance...

RF and microwave applications benefit greatly from the use of tunable devices and circuits. With components that can be tuned over a broad range, filters can be made to tune over multiple frequency bands of operation, impedance matching networks can be adjusted for amplifier power level or antenna impedance...
