Cellular and mobile broadband PC modem shipments grew more than 55 percent in 2009. In 2008, a total of 46.4 million such modems (including USB models, PC Card modems and wireless routers) shipped; in 2009, that figure grew to more than 72 million, according to the latest market data...

A Canadian horticulture research center has contracted with Raytheon Co. to install a prototype microwave frost protection system at its Ontario vineyard. Tempwave™ is a Raytheon-developed system that uses low-level microwave radiant heat to prevent frost damage to crops. Microwave energy is transmitted from towers located in an orchard...

Global mobile handset shipments totaled approximately 1.15 billion in 2009, with enhanced phones and smartphones capturing approximately 81 percent of all handset shipments, according to the latest data from ABI Research. According to Industry Analyst Celia Bo, "In recent years the major technology and application trends in handset design...

Boonton , a Wireless Telecom Group company, introduces a new, very fast 59340 Peak Power Sensor for frequencies up to 40 GHz. Wireless technology is getting increasingly demanding for test and measurement equipment. Highly dynamic signals, often with noise-like signal characteristics, fast switching carriers and pulsed signals, need to...

The current trend in the growing S-band market demands wider bandwidths, higher power levels and wider pulses, which are best served with a new technology to satisfy these advanced requirements. AlGaN/GaN HEMT on silicon substrate technology is a viable alternative to traditional technologies for high power transistors used in...

The Quartzlock E8000 represents a breakthrough in low cost, 1U rackmount, traceable, calibration-free "off air" frequency and time standards. It is a GPS controlled frequency and timing source, with both 10 MHz frequency output and 1 PPS timing mark synchronized to GPS time. Features include a holdover function on...

Figure 1 Families of equal power dividers. The "partial resistive divider" (PRD) is often overlooked when selecting a power divider circuit. This article compares its attributes with those of resistive, reactive and Wilkinson divider circuits. Figure 1 shows the basic resistive, reactive, partial resistive divider (PRD) and Wilkinson divider...

The Agilent Infiniium 90000 X-Series is a real time oscilloscope with 32 GHz of true analog bandwidth, and features the industry's lowest noise floor, lowest jitter measurement floor and flattest frequency response. This combination of performance results in a real time oscilloscope with industry leading accuracy. In addition, the...

GaAs MMIC Devices Freescale Semiconductor entered the GaAs MMIC marketplace with the introduction of four new devices designed and optimized specifically for high performance in macro base stations, repeaters and femtocells employed in wireless networks. The devices address low-noise amplifiers and transmit power amplifiers, two elements of wireless infrastructure...
