APPLICATIONS
• WCDMA/HSPA PCS-Band Wireless Handsets and Data Devices The AWT6278 HELP3TM PA is the 3rd generation WCDMA product for UMTS handsets.
This PA incorporates ANADIGICS’ HELP3TM 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
PRODUCT DESCRIPTION
