Fujitsu looks set to confirm its RF GaN pioneer status by selling WiMAX base stations based on wide-bandgap transistors, beginning in the second quarter of 2008.

The BroadOne WX300 outdoor macrocell base station uses the Japanese corporation's GaN HEMTs to provide wide-area transmission over a range of several kilometers.

The base station offers world-class efficiency and performance, Fujitsu says, and is the first of a wider series of BroadOne WiMAX transmitters due to be marketed worldwide.

“By combining energy efficiency with the world’s smallest base station enclosure, Fujitsu has significantly reduced the costs associated with installing and operating base stations,” the company claims.

The compact unit weighs only around 20 kg and occupies a volume of 20 liters, presumably offering cost benefits because it can be installed single-handedly.

The WX300 will operate in the 2.3 and 2.5 GHz frequency bands used by the emerging WiMAX standard, using two high-power output transceivers each containing three GaN HEMTs.
