Welcome to a Laptop Battery specialist of the Fujitsu Laptop Battery
Fujitsu Microelectronics Limited (FML) announced today 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.
Next-generation Mobile WiMAX technology will be deployed in the United States, Europe, and Taiwan this year, and in Japan next year. The initial service will be through PC-based mobile broadband access, with simultaneous with battery such as Fujitsu LifeBook T1010 Battery , Fujitsu LifeBook T2010 Battery , Fujitsu LifeBook T2020 Battery , Fujitsu Lifebook T4000 Battery , Fujitsu Lifebook T4000D Battery , Fujitsu Lifebook T4010 Battery , Fujitsu Lifebook T4010D Battery , Fujitsu LifeBook U810 Battery , Fujitsu LifeBook U820 Battery , Fujitsu Lifebook V1010 Battery , Fujitsu ST5022 Battery , Fujitsu ST5022D Battery development of handsets, smart phones, PDAs, portable games and navigation systems.
The chipset’s mature software stacks have been proven in the previous generation product, and the power management schemes have been optimized at the system level. These factors enable mobile WiMAX terminal manufacturers to focus on designing attractive user interfaces and service-oriented applications.
“This highly integrated WiMAX chipset features the low power and small form factor essential to the development of attractive mobile WiMAX terminal products,”said Makoto Awaga, General Manager of the Mobile Solution Business Group of Fujitsu Microelectronics Limited in Japan. “Fujitsu Microelectronics has assumed a global leadership position in moving WiMAX into deployment, and we are now ready to work with module vendors to meet market requirements.”
Chipset Key Features:
The MB86K22 is a fully integrated baseband LSI built using Fujitsu Microelectronics’ 65nm advanced CMOS low-leakage process technology. The operating power of the MB86K22 has been reduced by 36 percent from the previous generation. Power-gating technology shuts down the power supply in the unused blocks inside the device, so that the entire mobile WiMAX module consumes only 0.5mA, thereby extending battery life.
The MB86K52 is an RF LSI built using CMOS process technology, which supports 2.3GHz, 2.5GHz, and 3.5GHz, almost all the frequencies set by the WiMAX Forum. This offers mobile WiMAX terminal manufacturers the ability to introduce global WiMAX devices. The MB86K52 also supports MIMO and beamforming technology, which is essential for mobile WiMAX Wave 2.
The MB39C316 power management LSI eliminates all the complex and time-consuming power management requirements by accommodating one cell battery. This design minimizes the peripheral components outside of the module. The MB39C316 controls and manages the module’s power schemes at the system level, achieving the lowest power consumption at each operation.
