Skyworks PA Module For Quad-Band GSM And EDGE Powers LG's Shine Phone

Woburn, MA -- Skyworks Solutions, Inc. announced that it is supporting LG Electronics' ramp of its Shine handset. The Shine, which is LG's second model from its Black Label Series, is leveraging the SKY77340, a highly-integrated quad-band EDGE power amplifier. Skyworks' modules are also being utilized across LG's GPRS and CDMA Chocolate phones.

LG's Shine weighs 115 grams, stemming from its stainless steel material base. Its features, including expandable memory, an auto-focus, 20 megapixel camera, media player, Bluetooth and USB connectivity, have also helped fuel its consumer appeal.

"Skyworks is pleased to be supporting LG across a number of their most popular platforms," said Brian M. Daly, Skyworks' vice president of marketing. "Our integrated solutions and strong capabilities across all air interfaces allow LG and other handset manufacturers to produce feature-rich mobile phones with ground-breaking technology and unique design that have proven to be very popular with consumers."

LG announced at the end of March 2007 that Shine's sales volume in Europe exceeded the accumulated Shine sales in the Korean market a month after its launch.

The SKY77340 PAM is designed in a compact form factor for quad-band GSM and EDGE cellular handsets. Two separate heterojunction bipolar transistor (HBT) PA blocks are fabricated onto indium gallium phosphide (InGaP) die. Inputs and ouputs are impedance matched to 50 ohms, and a custom complementary metal oxide semiconductor (CMOS) integrated circuit (IC) provides internal multi function control (MFC) and interface circuitry.

The InGaP die, the silicon die, and passive components are mounted on a multi-layer laminate substrate and the assembly is encapsulated with plastic overmold. The circuitry regulates PA-bias conditions, reducing sensitivity to temperature, power supply, and process variation. The enable input signal provides a standby state to minimize battery drain. All of this comes in lead (Pb)-free, restriction of hazardous substances (RoHS)-compliant packaging.
