AWU6605
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 V
ENABLE
and V
MODE1
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 V
MODE1
.
The Bias Control table lists the recommended modes
of operation for various applications. V
MODE2
is not
necessary for this PA.
Two operating modes are available to optimize current
consumption. High Bias/High Power operating mode
is for P
OUT
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.
