F ujitsu Media Devices Limited, a manufacturer specialized in devices for mobile phone equipment, has developed the T0311QZ1950 (Band I), T0311QZ0836 (Band V), and T0312QZ1880 (Band II) - compact, high-performance transmitter modules with the world’s highest power efficiency for W-CDMA mobile phones. Fujitsu Media Devices will begin supplying successive samples of the modules from September. Fujitsu Media Devices is also planning to develop transmitter modules for Bands IV and VIII in an effort to further strengthen its product lineup. Fujitsu Media Devices is a pioneer in developing CDMA transmitter modules with built-in power amps for transmitting data to reduce the electrical connect and space requirements of RF parts in mobile phones.

Fujitsu transmitter modules for W-CDMA mobile phones - Features

1. The use of a proprietary duplexer and filter enables an optimal design and the world's highest level of power efficiency (27%). The transmitter modules support three output power modes: High power, Middle power, and Low power.

2. The transmitting circuit components of the mobile phone - the power amplifier, SAW filter, and SAW duplexer - are built into a single unit, thus the transmitter modules can achieve a compact size of 7.0 mm × 4.0 mm (with a maximum height of 1.2 mm). This enables a nearly 30 percent decrease in the circuit area when compared to modules configured using conventional discrete components.

3. These transmitter modules support High Speed Downlink Packet Access (HSDPA), which serves as the base for 3GPP Release 5, for downlink speeds of up to 14.4 Mbps.
