PRODUCT DESCRIPTION
TheAWU6608 HELP3TM PAis a 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. A “daisy chainable” directional
coupler is integrated in the module thus eliminating the
need of external couplers. 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 talk and standby time. The
self-contained 3 mm x 3 mm x 1 mm surface mount
package incorporates matching networks optimized for
output power, efficiency, and linearity in a 50 Ω system.

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 and VMODE1 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 VMODE1.
The Bias Control table lists the recommended modes
of operation for various applications. VMODE2 is not
necessary for this PA.
Two operating modes are available to optimize current
consumption. High Bias/High Power operating mode
is for POUT levels > 16 dBm. At around 17 dBm output
power, the PA can be “Mode Switched” to Medium/
Low power mode for lowest quiescent current
consumption.
