Fujitsu Microelectronics America
, a provider of Worldwide Interoperability for Microwave Access System on Chip technology, reportedly
announced the latest Mobile WiMAX (News
) baseband IC that supports a wide range of channel bandwidths including 3.5MHz, 5MHz, 7MHz, 10MHz, and 20MHz, along with 64QAM, 16QAM, and QPSK adaptive modulation schemes.
Featuring 36 percent power reduction and 60 percent space reduction from the original version, the MB86K23 is the successor to MB86K21 that targeted embedded WiMAX in mobile PCs and PC cards.
In addition to all the features required for Worldwide Interoperability for Microwave Access Forum Wave 2 mobile device certification, the new MB86K23 provides wireless access using 512/1024/2048 Fast Fourier Transform Orthogonal Frequency Division Multiple Access with integrated MAC processors. It also supports antenna diversity and “beam-forming.”
Designed for the expanding mobile PC market, the Fujitsu’s (News
) new WiMAX baseband IC is a low-power, small- footprint device. It is being manufactured using Fujitsu’s 65nm low-leakage complementary metal-oxide semiconductor process and CoolAdjust power-gating technology.
The CoolAdjust technology reduces power consumption during operation by switching off power to circuit blocks that are not in use. Additionally, it has the ability to reduce the standby current for an entire WiMAX module to 0.5mA, enabling significantly longer battery life in mobile devices.
The new WiMAX baseband IC also incorporates a USB interface, so designers can develop WiMAX USB adapters in ultra-small-form factors. Serial Peripheral Interface and Secure Digital Input/Output interfaces also are included.
“We expect mobile WiMAX to become a key broadband wireless access technology in many portable devices like Mobile Internet Device, Ultra Mobile PC, Tablets, and even low-cost handsets for emerging markets,” said George Wu, director of the Embedded Platform Solutions business group of Fujitsu Microelectronics America (News
). “This new baseband IC delivers the low power and small footprint required for these exciting applications.”
“We continue to apply Fujitsu’s leading-edge process technology and expertise to maximize performance,” Wu said. “The new MB86K23 represents an excellent design choice to serve the fast-growing global market for WiMAX-equipped systems.”
The new MB86K23 will be available in April.
