| Skyworks Powers LG's Shine Phone  Skyworks Solutions is supporting LG Electronics' ramp of its Shine handset. The Shine, which is LG's second model from its premium Black Label Series, is leveraging the SKY77340, a highly integrated quad-band EDGE power amplifier – used to support the world's largest markets in Europe and the United States. Skyworks' modules are also being utilized across LG's GPRS and CDMA Chocolate phones, which have sold ten million units globally since the end of 2005.LG's Shine weighs a mere 115 grams, stemming from its unique stainless steel material base. Its numerous features, including expandable memory, an auto-focus, 20 megapixel camera, comprehensive media player, Bluetooth and USB connectivity, have also helped fuel its exceptional consumer appeal. The SKY77340 PAM is designed in a compact form factor for quad-band GSM and EDGE cellular handsets. Two separate heterojunction bipolar transistor PA blocks are fabricated onto indium gallium phosphide die. Inputs and ouputs are impedance matched to 50 ohms, and a custom complementary metal oxide semiconductor integrated circuit provides internal multi function control 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, RoHS-compliant packaging. write your comments about the article :: © 2007 Computing News :: home page |
