ETS-Lindgren pioneered the over-the-air (OTA) performance testing market, designing and building the first CTIA Authorized Test Lab (CATL) for mobile station over-the-air antenna performance testing. Since then, the company has designed and built test chambers that have performed tests at some of the largest and best-known manufacturers of mobile...

Computer simulation is essential for the rapid design of efficient RF and microwave components. Not only can ‘what if?’ questions be posed and answered—sometimes in seconds—but once a viable design concept has been identified it can be optimized to achieve cost and performance targets. To facilitate this, parametric modeling...

Traditionally frequency counters have fallen into two main categories—general-purpose counters/timers and microwave counters. The former typically measure frequency from parts of a hertz to 200 to 300 MHz and can display frequency, time interval and period. Some general-purpose counters also provide ratio, phase comparison and low frequency burst measurement...

RF/Microwave Components Aeroflex/Weinschel is teaming with Argosy Component Sales to offer the industry’s largest selection of off-the-shelf RF and microwave components available. As Aeroflex/ Weinschel’s new stocking distributor, Argosy stocks a large selection of its coaxial attenuators, terminations, manual step and programmable attenuators, adapters, connectors, and other components for...

Ultronix is a Pennsylvania-based manufacturer of precision wirewound resistors. Angstrohm, based in Hagerstown, MD, is a manufacturer of wirewound rheostats. Elcom Technologies Inc. announced a...

Test and measurement (T&M) is one of the most dynamic sectors of our industry as rapidly developing technologies require complementary, parallel T&M development to support and augment their implementation. Technological advances are moving apace, particularly in the communications sector as manufacturers of handsets, wireless systems, etc. develop products to...

The second IEEE Radio & Wireless Week was held January 7–12, 2007, in Long Beach, CA, and was comprised of the IEEE Radio and Wireless Symposium (RWS), the IEEE Topical Symposium on Power Amplifiers for Wireless Communications (PAS), the Topical Meeting on Silicon Monolithic Integrated Circuits in RF Systems...

RF signals are undergoing dramatic changes as a result of the digital RF revolution. The RF spectrum is becoming increasingly crowded as wireless devices multiply. Marcus daSilva received his BS and MS degrees in electrical engineering from the University of Missouri-Rolla. He has held various engineering, management and marketing...

Emerging services and emerging markets were at the fore as the world's premier mobile event, the 3GSM World Congress 2007, enjoyed a second successful year in its Barcelona venue, with an increase in both the quantity and quality of visitors. Around 53,500 visitors (including all visitors, delegates, participants and...

Micronetics Inc. announced that its subsidiary Stealth Microwave Inc. has booked a production order from a systems integrator serving the US military totaling over $1.45 M for high performance power amplifiers used in IED jamming systems. David Robbins, president of Micronetics, stated, "We are pleased to provide our customers...
