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
MODE
voltages.
Bias Modes, Medium Bias Mode
The power amplifier may be placed in Low Bias mode
or a High Bias mode by applying the appropriate
logic level (see Operating Ranges table) to the
V
MODE1,
and V
MODE2
pins. The Bias Control table lists
the recommended modes of operation for various
applications.
