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 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.
