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 levels (see Operating Ranges
table) to the VMODE Voltage. The Bias Control table
lists the recommended modes of operation for
various applications.
