MMIC Technology for Broadband Wireless Access

The increasing role and volume of data communications combined with the convenience of wireless access provide the motivation for the development of high speed, compact, affordable and portable high data rate digital radios that can be integrated with notebook computers and function for extended periods of time on battery power. Such radios can be constructed only as a result of an intense development effort in wireless communication systems and continued integration of hardware. High communication speeds dictate multi-megahertz channels which are more readily available at higher frequencies. Recent history of local and wide area wireless communications suggests the requirement for speeds of 10 Mbps or more, best implemented in the NII and HIPERLAN bands at 5 GHz and beyond.
