Skyworks Solutions has announced that LG is leveraging its Helios power transceiver, the SKY74400, across its family of GPRS Chocolate phones launched in Europe and expanding to around the world later this year. LG's KG800 GPRS Chocolate tri-band handset, one of several models, has a touch-sensitive navigation, and features a hidden display and touchpad that glows when activated, thus becoming 'invisible' when not in use. Its design has proven very popular with consumers, having already sold six million units around the world since it debut in early May 2006 and achieving record sales in many countries. Other features include a high-quality MP3 music player, a multi-megapixel camera with flash and video recording, Bluetooth technology for wireless transmission of voice and data between compatible devices, 128 MB of onboard memory, and a high-resolution liquid crystal display screen.

The SKY74400 power transceiver is an integrated GPRS device for quad-band applications containing a direct conversion receiver and power amplifier with an integrated PA control function in a compact, 6 x 11 mm multi-chip module. The receiver path implements a direct down-conversion architecture that eliminates the need for intermediate frequency components, while the transmit path uses a translation loop architecture that provides frequency up-conversion with a high-spectral purity within the transceiver and a quad-band gallium arsenide heterojunction bipolar PA.
