RF Micro Devices Inc of Greensboro, NC, USA says it has started shipping its RF3161 quad-band large signal polar modulation (LSPM) EDGE power amplifier (PA) module to Huawei to support the ramp of its U120E 3G multi-mode (UMTS/EDGE) handset.

The highly integrated RF3161 is packaged in a compact 6mm x 6mm x 1mm package, making it the industry’s smallest and thinnest EDGE PA module in production, RFMD claims. The module is designed to support all major merchant market 3G multi-mode handset platforms implementing LSPM EDGE transmit architectures.

The RF3161 helps handset makers like Huawei to progress quickly and efficiently from layout to mass production of complex, next-generation handsets, claims Eric Creviston, corporate VP of RFMD’s cellular handset products group.

The U120E is the successor to Huawei’s high-volume U120 handset, which featured RFMD’s RF3166 PowerStar PA. “We look forward to supporting Huawei with new and innovative front-ends in future 3G multimode devices,” adds Paul Augustine, general manager of the component solutions business unit at RFMD. The firm anticipates that new, incremental EDGE-enabled handsets will feature its RF3161 as well as its high-efficiency RF3159 linear EDGE PA.

Meanwhile, Skyworks Solutions Inc of Woburn, MA, USA says that Huawei is leveraging multiple devices from its portfolio, including downconverters, front-end modules, power amplifiers, attenuators and switches, for both GSM and WCDMA base-station platforms.

Over the last several years, Huawei has partnered with some of the world’s top telecoms operators and gained market share. As a result, Skyworks’ sales to Huawei have tripled since 2004 and continue to grow, based on Huawei's increasing traction among worldwide carriers as it expands its domestic footprint in China to the broader global infrastructure market, says Liam K. Griffin, Skyworks’ senior VP sales & marketing. “Based on their business momentum, Huawei is becoming one of our largest infrastructure accounts as they leverage our highly integrated base-station solutions,” he adds.

Skyworks reckons that, on aggregate, it can capture up to $35 per base-station with RF-intensive WCDMA solutions compared to about $10 of content in a 2G base-station.
