New W-CDMA Transmitter Modules for Mobile Phones - Fujitsu

Fujitsu Media Devices introduced new transmitter modules for W-CDMA mobile phones. The modules are:  T0311QZ0836 for Band V, T0311QZ1950 for Band I,  and T0312QZ1880 for Band II. Fujitsu is also planning to develop transmitter modules for Bands IV and VIII.

Fujitsu Transmitter Modules for W-CDMA Mobile Phones

Key features of the new Fujitsu’s W-CDMA transmitter modules:

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.

Characteristics of Fujitsu T0311QZ1950 W-CDMA Transmitter Module (Representative data) :

• Power efficiency: 27 per cent in high power mode
• Adjacent leakage: -43dBm in High power mode * Offset = +/-5MHz
• Isolation: -28dBm (Tx to Rx in high power mode)
