Roke Manor Research Ltd. and Indra Sistemas S.A. have concluded agreements for the exclusive licensing to Indra of Roke's Vigilance™ technology for Wide Area Multilateration (WAM). The agreement gives Indra exclusive use of Roke's patents and know-how, for the manufacture, sales, support and further development of the Vigilance system...

Analog Devices Inc. (ADI), a leader in high-performance semiconductors for signal processing applications, introduced the ADF4602-1 transceiver for 3G femtocell base stations that support the universal mobile telecommunications system (UMTS) wireless interface standard for home and office wireless infrastructure equipment. The highly integrated direct conversion transceiver incorporates frequency synthesizers,...

AWR , a leader in high frequency electronic design automation (EDA), introduced the Digital Video Broadcasting (DVB) library for its Visual System Simulator (VSS) system-level design software. The library is compliant with the ETSI EN 300 744 V1.5.1 (2004-06) specifications and supports both Digital Video Broadcast - Terrestrial (DVB-T)...

Keithley Instruments Inc. , a leader in emerging measurement solutions, announced ACS Basic Edition, characterization and curve tracer software for component test applications. The latest addition to Keithley's powerful Automated Characterization Suite (ACS) family, ACS Basic Edition integrates with the industry's broadest range of source-measure units, Keithley's SourceMeter® Instrument...

This article describes the design and implementation of L-band frequency synthesizer based Local Oscillator to down-convert the uplink signal in a Telecommand Satellite Digital Receiver. An Integer-N PLL scheme was implemented to achieve a compact and low power module. The Local Oscillator when tested with the Receiver successfully achieved...

More than ten years ago LDMOS transistors were introduced as a replacement of bipolar transistors for RF power applications [1,2]. Nowadays LDMOS technology is the leading RF power technology for base station applications, in particular for GSM-EDGE applications at 1 and 2 GHz, WCDMA applications at 2.2 GHz and...

Two trends are well underway in portable and handheld consumer electronic devices: shrinking form factors and the integration of multiple wireless technologies, such as Bluetooth™, cellular, GPS and Wi-Fi. These trends create challenges for device vendors and integrators by increasing the likelihood of RF noise and other system interactions...

The Need to Amplify Signals An amplifier is one of the most common electrical elements in any system. The requirements for amplification are as varied as the systems where they are used. Amplifiers are available in a large number of form factors ranging from miniscule ICs to the largest...

In the ten years preceding the last Tri-Service Symposium (1960) on the “Biological Effects of Micro-waves,” a considerable community of researchers participated in the study of interaction of microwaves with biological systems, particularly animals and man. Military standards were confirmed at 10 mw/cm2 maximum permissible exposure levels based on...

Under the banner of 75 Years of Driving Innovation , Rohde & Schwarz invited more than 200 guests from around the world to celebrate its landmark 75 th anniversary at its state-of-the-art Technology Center in Munich, Germany, which opened in 2005. The Prime Minister of the State of Bavaria,...
