APPLICATION INFORMATION
AWC6312R
To ensure proper performance, refer to all related logic level (see Operating Ranges table) to the VMODE
Application Notes on the ANADIGICS web site: pin. The Bias Control table lists the recommended

modes of operation for various applications.
Shutdown Mode
The power amplifier may be placed in a shutdown mode
by applying logic low levels (see Operating Ranges
table) to both the VENABLE and VMODE1 voltages.
Bias Modes
The power amplifier may be placed in either a Low Bias
mode or a High Bias mode by applying the appropriate
Two operating modes are available to optimize current
consumption. High Bias/High Power operating mode
is for POUT levels > 16 dBm. At around 16 dBm output
power, the PA could be “Mode Switched” to Low power
mode for lowest quiescent current consumption.
