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
REF
and V
MODE
voltages.
Bias Modes
The power amplifier may be placed in either a Low
Bias mode or a High Bias mode by applying the
Table 5: Bias Control
appropriate logic level (see Operating Ranges table)
to the V
MODE
voltage. 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 V
CC
operating mode is for P
OUT
levels > 16 dBm. At
~16dBm - 7 dBm, the PA should be “Mode Switched”
to Low Bias Mode. For P
OUT
levels < ~7 dBm, the V
CC
can be switched to 1.5 V (Low Bias Mode is also
used for this P
OUT
range).
