TriQuint unveils broadband WCDMA solution for ST-Ericsson platforms

RF front-end product maker and foundry services provider TriQuint Semiconductor Inc of Hillsboro, OR, USA has added to its TRIUMF (TriQuint Unified Mobile Front-end) Module family (launched in February 2009) with the TQM7M9070, a broadband power amplifier module (PAM) that aligns with ST-Ericsson’s MM5730 and U5500 platforms.

TriQuint says that the new module’s integration technology offers 3G designers building global smartphones and other mobile devices a streamlined RF footprint, through support for multiple modulations and multiple bands in one module.

In addition to reducing the component count, the power amplifier provides WCDMA/HSUPA modulation over multiple bands by enabling what is claimed to be outstanding power-added efficiency (PAE) — a critical contributor to longer battery life — without requiring a DC-to-DC converter.

In close collaboration with ST-Ericsson, all system-critical parameters will be verified as a platform reference design. “The solution has been tested and works together to deliver a new level of power added efficiency,” says Tim Dunn, VP & general manager of Mobile Devices. “Given the real-estate limitations in today’s devices, our new broadband power amplifier module offers a competitive advantage to our customers since it reduces the transmit area by more than 20%, and optimizes the electrical RF performance for each unique device,” he adds.

The new broadband power amplifier supports WCDMA high bands 1, 2 & 4, and WCDMA low bands 5, 6 & 8. Its scalability from dual-band to penta-band applications addresses the demand for mid- to high-end feature and smartphones. Enabled by TriQuint’s CuFlip technology, the broadband PAM inherently manages heat in a small form factor of 5mm x 4mm x 1mm.

Complementary to the TQM7M9070, TriQuint offers the highly efficient TQM7M5022R quad-band power amplifier module for GSM/EDGE to support a complete amplification solution for any cellular multimode/multiband application.

TriQuint will highlight its RF platform solutions at the telecom industry’s largest annual gathering, GSMA Mobile World Congress 2011 in Barcelona, Spain (14–17 February).
