AWT6628A

The AWT6628A HELP4^TM PA is a 4th generation HELP^TM product for WCDMA devices operating in UMTS900 (Band 8) . This PA incorporates ANADIGICS’ HELP4^TM technology to deliver exceptional efficiency at low power levels and low quiescent current without the need for external voltage regulators or converters. The device is manufactured using advanced InGaP-Plus^TM HBT technology offering state-of-the-art reliability, temperature stability, and ruggedness. Three selectable bias modes that optimize efficiency for different output power levels and a shutdown mode with low leakage current increase handset talk and standby time. A "daisy chainable" directional coupler is integrated in the module, thus eliminating the need of an external coupler. The self-contained 3 mm x 3 mm x 1 mm surface mount package incorporates matching networks optimized for output power, efficiency, and linearity in a 50  system.
