Shutdown Mode
The power amplifier may be placed in a shutdown
mode by applying a logic low levels (see Operating
Ranges table) to both the VEN and VMODE voltages.
Power Modes
The power amplifier may be placed in either a Low
Power mode or a High Power mode by applying the
appropriate logic level (see Operating Ranges table)
to the VMODE voltage. The Power Control table lists
the recommended modes of operation for various
applications.
