Industry standards bodies — such as the 3GPP Standards organization governing global cellular networks such as GSM, PCS, EDGE and WCDMA — are traditionally chartered to create a stable business environment for advancing technology in a competitive market. These industry standards — as simple as the pitch of a...

RF-MEMS switches offer a number of advantages for switching in the gigahertz range because of their low insertion loss, high linearity and low power consumption. 1 Several publications have reported on the performance of such switches, but more for non-packaged ‘naked’ samples. It is clear that the packaging process...

The temperature stability of the RF output power level has become especially important for different handheld wireless communication systems. For GSM mobile handsets, an analog closed-loop power control, incorporated in the transmitter power amplifier (PA) chain, allows the main parameters of the PA to be stabilized over the ambient...

Welcome to the 2006 IEEE Radio and Wireless Symposium and the weeklong MTT Wireless event. We have planned the symposium and the overall event to give you the opportunity to learn about the latest in wireless systems, technologies, components, implementations, products and tools in a single week and in...

In Part I of this tutorial article, 1 a detailed discussion and analysis of the start-up and steady-state oscillation conditions for transistor LC oscillators was given, with emphasis on CMOS devices. Part II 2 presented both linear and nonlinear phase noise models for parallel feedback and negative resistance oscillators....

Northrop Grumman Corp. has successfully demonstrated the capabilities of an advanced high power amplifier for the US Army that is capable of enabling critical communications for the network-centric Future Force. Army Future Force concepts include information superiority and improved situational understanding through the integration of data from joint forces....

The Aegis Ballistic Missile Defense (BMD) Weapon System successfully detected and tracked an unarmed US Air Force Minuteman III intercontinental ballistic missile (ICBM). Aegis detected the missile when it rose above the horizon and immediately began BMD tracking operations. Lockheed Martin develops the Aegis BMD Weapon System for the...

Harris Corp. has been awarded a competitive procurement contract to supply the US Marine Corps’ Multiband, Multimission Radio (MBMMR) Standardization Program with its combat-proven Falcon“ II AN/117(C) radios. The first delivery orders of $67 M have been awarded as part of a multi-year $205 M blanket purchase agreement. Deliveries...

Ericsson to Acquire Key Assets of Marconi’s Telecommunications Business Ericsson has reached an agreement with Marconi Corp. plc to acquire the parts of the company’s telecommunications business that are strategically important to Ericsson. Ericsson will acquire assets representing about 75 percent of Marconi’s turnover and will pay approximately £1.2...
