Mobile WiMAX – 802.16e-2005 RF Module (MB86K71)

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, antenna switches, a power amplifier, filters, and an oscillator circuit, 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 supports MIMO and beamforming 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, MB86K21, enabling customers faster development and faster time to market of Mobile WiMAX devices through the use of both of these chips.

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 (with height 1.5mm) which will contribute to a reduction in the form-factor of Mobile WiMAX devices.
2. High-speed, reliable connections using MIMO and beamforming
   This product supports MIMO and beamforming, which utilizes multiple antennas, to achieve high-speed and reliable wireless connections. This product also supports WiMAX Forum's Wave 2 specifications.
