New WiMAX SoC from Fujitsu can enable
the design of WiMAX dongle
Fujitsu has introduced a new mobile WiMAX baseband IC
in small-footprint. The idea of pluggable USB adapters in
mobile devices can be implemented using this device.
The new Fujitsu MB86K23 mobile WiMAX baseband IC supports
a wide range of channel bandwidths including 3.5MHz, 5MHz,
7MHz, 10MHz, and 20MHz, along with 64QAM, 16QAM, and QPSK
adaptive modulation schemes. It provides wireless access
using 512/1024/2048 FFT OFDMA with integrated MAC processors,
supports antenna diversity and beamforming, and includes
all the features required for WiMAX Forum Wave 2 mobile
device certification.
The MB86K23 is being manufactured using Fujitsu's 65nm
low-leakage CMOS process and CoolAdjust power-gating technology,
which reduces power consumption during operation by switching
off power to circuit blocks that are not in use. Standby
current for an entire WiMAX module can be reduced to 0.5mA,
enabling significantly longer battery life in mobile devices.
The new WiMAX baseband IC incorporates a USB interface,
so designers can develop WiMAX USB adapters in ultra-small-form
factors just like wifi or bluetooth dongles. SPI and SDIO
interfaces also are included.
"We expect mobile WiMAX to become a key broadband
wireless access technology in many portable devices like
Mobile Internet Device (MID), Ultra Mobile PC (netbooks),
Tablets, and even low-cost handsets for emerging markets.
This new baseband IC delivers the low power and small footprint
required for these exciting applications," said George
Wu, Director of the Embedded Platform Solutions business
group of Fujitsu Microelectronics America. "We continue
to apply Fujitsu's leading-edge process technology and expertise
to maximize performance. The new MB86K23 represents an excellent
design choice to serve the fast-growing global market for
WiMAX-equipped systems."
The MB86K23 is the successor to the Fujitsu mobile WiMAX
baseband IC, the MB86K21, which targeted embedded WiMAX
in mobile PCs and PC cards. In comparison to MB86K21, MB86K23
offers 36% power reduction, 60% space reduction.
When combined into a chipset with the Fujitsu MB86K52 RF
IC and MB39C316 power-management IC, the MB86K23 enables
developers to realize the industry's most compact form factors
- just 20mm x 40mm for WiMAX USB adapters, and 30mm x 26.8mm
for PCI Express half-mini cards that incorporate both WiMAX
and Wi-Fi functionality.
ODM vendors are now planning to release these kinds of
products using this WiMAX baseband IC. In addition to its
low power requirements and small footprint, the Fujitsu
MB86K23 can use software that was developed for the MB86K21,
which has passed compatibility testing with many base stations.
