WiQuest Communications , a fabless semiconductor company developing complete ultrawideband (UWB) solutions, announced the availability of its WQST110 and WQST101 chipset, the industry's first commercially-available, high performance silicon delivering wireless communication speeds up to one gigabit-per-second. Based on the WiMedia UWB physical layer (PHY) and media access controller (MAC)...

Cascade Microtech has developed WinCal 2006™ with new software tools to address the many testing challenges brought on by the increase in the volume of complex, high speed semiconductors that are designed for use in mobile communications products such as cell phones, PDAs and laptop computers. Compounding the multi-gigabit...

Leaping ahead in the race to deliver more and more functionality and value to the handset maker, Skyworks Solutions has introduced the industry’s best transmit front-end solution (SKY77506) for GSM/GPRS segment. Two InGaP HBT power amplifiers (PA), a BiCMOS power controller and two PHEMT-based RF switches have been integrated...

Industry standards bodies — such as the 3GPP Standards organization governing global cellular networks such as GSM, PCS, EDGE and WCDMA — are traditionally chartered to create a stable business environment for advancing technology in a competitive market. These industry standards — as simple as the pitch of a...

RF-MEMS switches offer a number of advantages for switching in the gigahertz range because of their low insertion loss, high linearity and low power consumption. 1 Several publications have reported on the performance of such switches, but more for non-packaged ‘naked’ samples. It is clear that the packaging process...

The temperature stability of the RF output power level has become especially important for different handheld wireless communication systems. For GSM mobile handsets, an analog closed-loop power control, incorporated in the transmitter power amplifier (PA) chain, allows the main parameters of the PA to be stabilized over the ambient...

Welcome to the 2006 IEEE Radio and Wireless Symposium and the weeklong MTT Wireless event. We have planned the symposium and the overall event to give you the opportunity to learn about the latest in wireless systems, technologies, components, implementations, products and tools in a single week and in...
