Fujitsu Launches World's Smallest RF Module for Mobile WiMAX Devices; Supports MIMO Technology Enabling High-speed, Reliable Communication

 BroadOne WX300 Macro Base Station
Tokyo, Feb 7, 2008 - (JCN Newswire) - Fujitsu Limited today announced the launch of the world's smallest radio frequency(RF) module for mobile devices, which supports all of the RF circuitry necessary for Mobile WiMAX[1], the highly anticipated next-generation broadband wireless technology. The new RF module, MB86K71, co-developed with Fujitsu Laboratories Limited, was designed using 90-nanometer CMOS process technology. Sample shipment is scheduled to start at the end of February 2008.

This new RF module from Fujitsu, the world's smallest to feature all of the RF circuits necessary for Mobile WiMAX devices including RF-IC[2], antenna switches, a power amplifier, filters, and an oscillator circuit[3], measures just 15mm x 15mm (height: 1.5mm) in dimension. Thus, this RF module will enable significant reduction of the form-factor of Mobile WiMAX devices.

The new RF module also supports MIMO[4] technology, thereby enabling high-speed and reliable wireless connections that are essential for Mobile WiMAX devices. Furthermore, Fujitsu also verified that this RF module can be connected to Fujitsu's previously released Mobile WiMAX baseband chip[5], MB86K21, enabling customers faster development and faster time to market of Mobile WiMAX devices through the use of both of these chips.

Fujitsu will exhibit this RF module at the GMSA Mobile World Congress 2008 to be held in Barcelona, Spain, from February 11-14, 2008. (Stand J45, Hall 1)

Mobile WiMAX is a next-generation broadband wireless technology featuring data transmission that is faster than that of 3G cellular networks, and wider coverage than existing wireless LANs. Mobile WiMAX service is scheduled to start in the U.S and Taiwan in 2008, followed by Japan where the service is scheduled to start in 2009. With this ramp-up of WiMAX, opportunities for new markets and services are expected to be created.

Fujitsu will continue to pursue the integration of baseband chips and RF modules, and in addition to adding products to its line-up which will feature even lower power consumption and smaller form-factors, Fujitsu aims to contribute to the expansion of the Mobile WiMAX market through the further miniaturization of RF-IC.


Key Features

1. World's smallest RF module realized by utilizing 90nm CMOS process technology

With the RF-IC fabricated in 90nm CMOS process technology, combined with antenna switches, a power amplifier, filters, and an oscillator circuit, all the necessary RF circuits for a Mobile WiMAX device are in one module. Subsequently, the world's smallest size module was realized, with dimensions 15mm x 15mm (height 1.5mm) which will contribute to a reduction in the form-factor of Mobile WiMAX devices.

2. High-speed, reliable connections using MIMO

This product supports MIMO, which utilizes multiple antennas, to achieve high-speed and reliable wireless connections. This product also supports WiMAX Forum's Wave 2[6] specifications.
