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 VREF and VMODE 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 VMODE voltage. The Bias Control table lists the
recommended modes of operation for various
applications.
