PRODUCT DESCRIPTION
The AWT6281 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
current, increase handset talk and standby time. The
self-contained 4 mm x 4 mm x 1 mm surface mount
package incorporates matching networks optimized for
output power, efficiency, and linearity in a 50 Ω system.

APPLICATION INFORMATION
To ensure proper performance, refer to all related voltages. The Bias Control table lists the recommended
Application Notes on the ANADIGICS web site: modes of operation for various applications.

The power amplifier may be placed in a shutdown mode is for POUT levels > 16 dBm. At ~16dBm - 7
mode by applying logic low levels (see Operating dBm, the PA should be “Mode Switched” to Medium
Ranges table) to the VENABLE, VMODE1 and VMODE2 Bias Mode. For POUT levels < ~8 dBm, the PA can

be switched to Low Bias/Low Power Mode used for
this POUT range for even lower quiescent current
consumption.
Bias Modes
The power amplifier may be placed in either a Low Bias
mode or a High Bias mode by applying the appropriate
logic level (see Operating Ranges table) to the VMODE
