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 both 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 the V
MODE
pin. The Bias Control table lists the recommended
modes of operation for various applications.
Two operating modes are available to optimize current
consumption. High Bias/High Power operating mode
is for P
OUT
levels
>
16 dBm. At around 16 dBm output
power, the PA could be “Mode Switched” to Low power
mode for lowest quiescent current consumption.
