The program for this year’s International Microwave Symposium (IMS), the annual conference and exhibition of the IEEE Microwave Theory and Techniques Society (MTT-S), is now available. The IMS 2009 conference will feature 430 technical presentations, organized in four technical tracks: Microwave Modeling; Active Components; Passive Components; and Microwave Systems....

Micronetics Inc. announced that its New Jersey-based subsidiary, Microwave Concepts (Micro-Con), has received advanced funding of approximately $5 M from a major defense OEM for highly integrated microwave subassemblies. These subassemblies are used as part of a complex jamming system. In addition to this advanced funding, full funding of...

Harris Stratex Networks Inc. , a specialist in backhaul solutions for mobility and broadband networks, introduced an enhanced Eclipse™ Packet Node wireless backhaul solution to enable North American mobile operators to support next-generation mobile broadband services. The enhanced Eclipse Packet Node, which includes the new IRU600 all-indoor radio unit,...

Power amplifiers are important components in almost all wireless communication systems. They normally consume large amounts of power, and therefore play a critical role in battery life for mobile devices. As a rough estimate, in a typical WiMAX radio, the baseband and transceiver will consume about 600 mW, whereas...

An overview of the 28-42-50 V LDMOS technologies is given and the ruggedness reliability is discussed, in addition to the RF performance. Various ruggedness tests are presented such as pulsed snapback measurements, VSWR and video bandwidth tests. RF power amplifiers are key components in base stations, broadcast transmitters, ISM...

All quartz crystal oscillators are affected by acceleration. While for many applications the effects are negligible, in those where frequency stability is critical and the environment is physically demanding (high shock or vibration), the effects can be significant. Even devices that are operated in relatively benign locations are under...

Communication systems today comprise the major use of GaAs technology with the highest volumes found in the cellular handset front-end. Here, heterojunction bipolar transistor (HBT) power amplifiers (PA) and Pseudomorphic High Electron Mobility Transistor (PHEMT) switches enjoy a comfortable market share. In this environment, the demands of production design...

EM Research has developed the ZLX Series of drop-in frequency synthesizers with models operating from 800 MHz to 3.8 GHz that are replacements for many industry standard PLOs and synthesizers. The ZLX Series is a cost-effective replacement that provides design engineers with improved signal source performance without any need...

Over the past 50 years crystal oscillators have become ubiquitous wherever a stable reference is needed in RF systems. Oven-controlled Crystal Oscillators (OCXO) in the 5 to 10 MHz range are typically used to provide very stable frequency references, or where ultra-low phase noise is required very close to...

Industry News IEEE , the world’s largest technical professional society, signed a merger agreement with the honor society Eta Kappa Nu (HKN), a nonprofit, public-service organization comprising nearly 200 university chapters. The merger, which will go into effect by mid-2009 pending final approval, will make HKN the official honor...
