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.

The device may be operated safely over these conditions; however, parametric performance is guaranteed only
over the conditions defined in the electrical specifications.
Notes:
(1) For operation at Vcc = +3.2 V, Pout is derated by 0.5 dB.

APPLICATION INFORMATION
To ensure proper performance, refer to all related
Application Notes on the ANADIGICS web site:
http://www.anadigics.com
Shutdown Mode
The power amplifier may be placed in a shutdown
mode by applying logic low levels (see Operating
Ranges table) to the VENABLE, VMODE1 and VMODE2
voltages.
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
voltages. The Bias Control table lists the recommended
modes of operation for various applications.
Three operating modes are recommended to optimize
current consumption. High Bias/High Power operating
mode is for POUT levels > 16 dBm. At ~16dBm - 7
dBm, the PA should be “Mode Switched” to Medium
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.
