WCDMA Front-end Modules and Their Critical Role in 3G Wireless Handsets

Introduction to a WCDMA front-end module that combines GSM SAW Rx filters, a multi-mode switch and transmit harmonic filters into an ultra-small footprint

Performance, cost and size are key to mobile phone design. Improved performance, lower cost and ever-shrinking module size parameters are universal challenges in the competitive world of mobile phone manufacturing. Over the past four years steady improvements have been made in power amplifier efficiency. Prices have likewise dropped. Yet...

A new high voltage, high power InGaP HBT discrete device has been developed that can significantly improve the efficiency of power amplifiers (PA) in cellular base stations. This new technology provides superior performance compared to silicon LDMOS. A 30-watt device driven by a predistorted W-CDMA signal has demonstrated 45...

Two broadband satellite networks are in the final stages of development and plan a service launch for North America in early 2004. Systems like these are expected to provide wideband, high speed communications for Internet and multimedia applications across North America and Europe for years to come. High power...
