Fujitsu Microelectronics Limited announced a new mobile WiMAX chipset optimized for mobile WiMAX devices such as smart phones and PDAs. Sample shipment will start in August 2008. The chipset includes a baseband LSI, the MB86K22; an RF LSI, the MB86K52; and a power management LSI, the MB39C316. The three devices are essential elements for competitive WiMAX modules. The chipset was designed so that the size of the WiMAX module will be 12x12mm. The standby current - which has a direct impact on battery life - will not exceed 0.5mA, facilitating the development of attractive mobile WiMAX terminals. |
