Mobile WiMAX System Comes Packaged In One Chip

Fujitsu Microelectronics America just announced their forthcoming highly integrated 802.16e mobile WiMAX PHY and MAC mixed-signal chip. To be built with Fujitsu's 90 nm process, the chip is designed to optimize both performance and power consumption for mobile terminals. While their fixed 802.16-2004 WiMAX chip has been available for a while, this one is directed at the much awaited mobile version of WiMAX that some say will finally make WiMAX viable. The new SoC includes a scalable 1024 fast Fourier transform (FFT) OFDMA PHY and full MAC processors with adaptive modulation including BPSK, QPSK, 16QAM AND 64QAM. A key feature is the inclusion of the interface to handle a 2 x 2 MIMO front-end tuner. MIMO is defined as part of the 802.16e standard and is expected to make mobile WiMAX an excellent performer in highly mobile applications. The final test and evaluation is being completed this year with samples of the chip being available early in 2007.
