News Comment Cover feature: How to succeed as a GaAs foundry The Foundry model in the semiconductor business has been an important component for enabling the growth of many electronics markets. Gallium Arsenide (GaAs) foundry suppliers enable companies to access state of the art GaAs semiconductor technology to build high speed RFIC and MMIC products without the capital investment required for a major manufacturing facility. So what does it take to be successful as a GaAs foundry? Wireless networking: Wireless coverage where everybody WINS Whether standing on the thirtieth floor of a skyscraper or seated in a subway, today’s consumers want wireless phone and data access whenever and wherever they are. Peter Raabe, Director Global Product Management and Support for Wireless Indoor Solutions at Radio Frequency Systems, explores the new generation of wireless indoor infrastructure. Wireless networking: Achieving good coexistence in the 2.4 GHz ISM band As the worldwide open 2.4 GHz ISM band becomes ever more crowded, good coexistence becomes vital to the successful deployment of an RF solution. The two most important factors to achieve good coexistence are selectivity and frequency hopping/agility algorithm. GPS and Satellite: GPS developments: Galileo moves forward with successful Giove-B satellite launch — Broadcom targets AGPS in mobile phones and devices Raising the bar for the radio: Making 802.11n work Power amplifier design for a WLAN radio poses a challenge when meeting specifications. It is more challenging than ever to define and achieve the levels of radio-frequency performance required to meet the 802.11n standard in increasingly small portable and mobile applications.
