Description:
The AWT6281 HELP3™ PA is the 3rd generation WCDMA product for UMTS handsets. This PA incorporates ANADIGICS’ HELP3™ technology to provide low power consumption without the need for an external voltage regulator. The device is manufactured on an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. There are 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. The self-contained 4 mm x 4 mm x 1.1 mm surface mount package incorporates matching networks optimized for output power, efficiency, and linearity in a 50 Ω system.
Features:
• InGaP HBT Technology
• High Efficiency:
42 % @ POUT = +29 dBm
21 % @ POUT = +16 dBm
8.5 % @ POUT = +8 dBm
(without DC/DC Converter)
