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 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
logic level (see Operating Ranges table) to VMODE1.
Table 6: Bias Control
The Bias Control table lists the recommended modes
of operation for various applications. VMODE2 is not
necessary for this PA.
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 should be “Mode Switched” to
Medium/Low power mode for lowest quiescent current
consumption.
