A 2.469-2.69GHz AlGaN/GaN HEMT Power Amplifier for IEEE 802.16e WiMAX Applications

WiMAX, with the whole name Worldwide Interoperability of Microwave Access, is a new broadband wireless access technique which is based on IEEE 802.16 standard. The basic object of WiMAX is that, under the environment of Metropolitan Area Network it makes the wireless devices from different manufacturers connect together. The standards defined by IEEE for different scenarios are showed. This technique mainly provides the "Last kilometer" high-speed broadband access for family, enterprise and mobile communication networks, even for the personal mobile communication business in the future. It uses a lot of advanced technologies which represent the direction of the development of communication in the future.
