AWT6624
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
EN
, V
MODE1
and V
MODE2
voltages.
Bias Modes
The power amplifier may be placed in either Low,
Medium or High Bias modes by applying the
appropriate logic level (see Operating Ranges table)
to the V
MODE
pins. The Bias Control table below lists
the recommended modes of operation for various
applications.
Three operating modes are recommended to optimize
current consumption. High Bias/High Power operating
mode is for P
OUT
levels > 16 dBm. At ~17dBm - 7 dBm,
the PA could be switched to Medium Power Mode. For
P
OUT
levels < ~8 dBm, the PA could be switched to Low
Power Mode for extremely low current consumption.
