Anadigics has begun volume shipments of its AWT6277 WCDMA power amplifier modules to LG Electronics for use in the new LG Viewty (LG-KU990), a 5.0-Mpixel professional-level camera phone currently available in the UK. Specifically designed to meet the needs of feature-rich mobile handsets, the AWT6277 includes Anadigics’ HELP technology, which reduces WCDMA average power consumption by 50%. Combined with low leakage current in shutdown mode, the AWT6277 PA delivers longer battery life and additional talk time—two key metrics for mobile handset designers.
The self-contained 4-mm by 4-mm by 1.1-mm surface-mount PA incorporates matching networks optimized for output power, efficiency, and linearity in a 50-Ω system. This integration reduces device footprint and the need for external components, making it extremely well suited for super-thin designs. AWT6277 HELP PA is enabled by Anadigics’ patented InGaP-Plus HBT technology, which combines InGaP HBT and pHEMT devices on the same die and delivers state-of-the-art performance, reliability, temperature stability, and ruggedness.
Besides 5.0-Mpixel resolution, the LG Viewty features auto and manual focus, image stabilization, and a handwriting editing function. The video camera on this candy bar-form handset can also take video at up to 120 frames per second. With just one click, users can upload a recorded video directly to Google’s YouTube and share it with the world. The 3.0-in. full touch screen enables users to enjoy high quality DivX video files in wide-screen format.
