The AWT6651 PA is designed to provide highly linear output for WCDMA, CDMA, LTE and TD-SCDMA handsets and data devices with high efficiency at both high and low power modes. This ProEficientTM PA can be used with an external switch mode power supply (SMPS) to improve its efficiency and reduce current consumption further at medium and low output powers. The device is manufactured on an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. There are two selectable bias modes that optimize efficiency for different output power levels, and a shutdown mode with low leakage current, which increases handset talkand standby time. The self-contained 3 mm x 3 mm x 0.9 mm surface mount package incorporates matching networks optimized for output power, efficiency, and linearity in a 50 Ω system.
