The IEEE 802.22 working group has passed a major milestone in the development of the IEEE P802.22™ standard, which aims to use geographically unused TV channels to bridge the “digital divide” between rural and outer-suburban areas and major urban centers. The milestone involves the acceptance of a single, unified...

The Strategy Analytics annual five year outlook for the gallium arsenide microelectronics industry, “GaAs Industry Forecast: 2005–2010,” predicts that GaAs device revenues will grow by 36 percent over 2005 to 2010, breaking the $3 B barrier in 2006. Overall market growth will continue to be derived from wireless markets,...

Revenue growth for sales of MEMS devices worldwide slowed dramatically in 2005, despite the fact that unit shipments were very strong, reports In-Stat. Nearly 1.8 billion MEMS devices were shipped in 2005, generating revenues of just under $7 B, the high tech market research firm says. In-Stat found that...

Radio frequency identification (RFID) is an area of automatic identification that has quietly been gaining momentum in recent years and is now being seen as a radical means of enhancing data handling processes, complementary in many ways to other data capture technologies such as bar coding. RFID systems involve...

Due to the fast development of wireless communications, a low cost, high performance, highly integrated technology is needed for system-on-a-chip (SoC) implementations. The CMOS technology provides a good solution for SoC integration. 1 Recent improvements of the standard CMOS process make it possible to implement RF blocks, such as...

In Part I of this article, 1 a number of experimental results were presented, suggesting that interactions in arrays of tag antennas play an important role in determining when a UHF RFID tag can be read, even when no other scattering is present in the environment. How can these...

Up until a few years ago, it was only possible to fabricate radio frequency power amplifiers (RFPA) in the VHF band by using bipolar transistors, because the devices designed in vertical MOS technology (VMOS), which were the only MOS power devices available at that time, were not able to...

With the ever-increasing complexity in today’s high frequency and high speed circuit designs, designers appreciate the development time and cost savings that can come from accounting for electromagnetic (EM) effects up-front in designs. However, many designers still see EM point tools as an expensive luxury that is best left...

RF Amplifier Systems and Modules This redesigned web site features a new search tool that allows users to search by keyword, power, power option and/or frequency. AR Worldwide Modular RF manufactures RF amplifier systems and modules for wireless communications, military communications, and a variety of medical, scientific and industrial...

RF Power MOSFET The model ARF475FL is a high voltage, flangeless packaged, RF power MOSFET that utilizes a newly-patented process and finer geometry to deliver high peak power and RF gain. These MOSFETs operate reliably at DC voltages up to 165 V. The ARF475FL utilizes two die, configured for...
