Fujitsu 2nd Generation Mobile WiMAX Chipset for Embedded Modules

MB86K22, MB86K52, MB39C316

MB86K22 Baseband IC
This fully integrated baseband IC was built using the Fujitsu 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, extending battery life. This IC, which is fully compliant with the IEEE 802.16e-2005 standard utilizing scalable OFDMA PHY, operates in Time Division Duplex (TDD) mode. The chip supports multiple operating frequency and channel bandwidth profiles, as well as various subcarrier allocation schemes.

MB86K52 RF IC
This RF IC, which was built using CMOS process technology, supports 2.3GHz, 2.5GHz, and 3.5GHz, almost all the frequencies set by the WiMAX Forum™. This offers mobile WiMAX terminal manufacturers the opportunity to develop global WiMAX devices. The MB86K52 also supports MIMO and beamforming technology, which are essential for mobile WiMAX Wave 2. Fujitsu’s mobile WiMAX RF LSI fully complies with the IEEE 802.16e-2005 standard and can support multiple operating frequency bands with several channel bandwidths. At the same time, MB86K52 provides a lower noise figure (NF) at the receiver and better error vector magnitude (EVM/RCE) at the transmitter when compared to the previous generation RF ICs. The chip connects to a baseband IC through a 4-wire SPI interface and analog IQ interfaces. When paired with Fujitsu’s baseband solution, the RF IC is able to conduct auto-IQ mismatching calibration, which further improves system performance. This mobile WiMAX RF LSI can also be utilized by next-generation PHS technology based on orthogonal frequency division multiplexing.

MB39C316 power management IC
The MB39C316 power management IC 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.
