TriQuint launches multimode system using integrated modules

TriQuint Semiconductor Inc. has launched a new multimode system solution using highly integrated modules to support all global standards from 2G GSM/GPRS to the latest multimedia-centric 3G standards, including HSUPA. The four compact modules provide a global solution for quad-band GSM/GPRS/EDGE and tri-band WCDMA/HSUPA, all from a single antenna, and are aligned with Infineon's SMARTi UE transceivers.

The new modules include the TQM676021, TQM666022 and TQM616025 TRITIUM III PA-Duplexer Modules, and the TQM6M9008, the first member of the QUANTUM II Tx Module family.

The TRITIUM III PA-Duplexer Modules are high data-rate HSUPA compliant and support Band 1, Band 2 and Bands 5/6. The 7-by-4mm footprint is 30-per cent smaller than previous designs, leaving more board space for handset manufacturers to add features such as cameras, Wi-Fi and Bluetooth connectivity. Each highly integrated TRITIUM III PA-Duplexer Module includes a power amplifier, duplexer and Tx interstage filter and a coupler/detector, which eliminate multiple discrete devices and reduce phone development time. The high-efficiency architecture is optimised to reduce battery consumption, increasing the time between charges, said TriQuint.

The TQM6M9008 QUANTUM II Tx Module combines a GSM/EDGE power amplifier, WEDGE (W-CMDA + EDGE) antenna switch, filtering and CMOS controller into one 7-by-7.5mm module. The TQM6M9008 is said to improve time to market with a plug-and-play solution that requires no customisation by the handset manufacturers to work across multiple handset form factors such as traditional, flips and sliders, all on a common platform. It also helps reduce the number of dropped calls by exceeding the network operator's Total Radiated Power (TRP) requirements, which tests the effective level of radiated power while the phone is in a transmit mode. The new TRP circuitry senses the signal degradation in these environments and adjusts the power amplifier performance to reduce the number of dropped calls while simultaneously optimising power consumption for improved battery life, said the company.

TriQuint is currently sampling both the TRITIUM III PA-Duplexers and QUANTUM II Tx Modules to lead customers. Customers interested in obtaining samples and evaluation boards should contact info-handsets@triquint.com.
