APPLICATION INFORMATION  
To ensure proper performance, refer to all related logic level (see Operating Ranges table) to the VMODE  
Application Notes on the ANADIGICS web site: voltages. The Bias Control table lists the recommended  
http://www.anadigics.com  
modes of operation for various applications.  
Shutdown Mode  
Three operating modes are recommended to optimize  
The power amplifier may be placed in a shutdown current consumption. High Bias/High Power operating  
mode by applying logic low levels (see Operating mode is for POUT levels > 16 dBm. At ~16dBm - 7  
Ranges table) to the VENABLE, VMODE1 and VMODE2 dBm, the PA should be “Mode Switched” to Medium  
voltages.  
Power Mode. For POUT levels < ~8 dBm, the PAcan be  
switched to Low Power Mode for even lower quiescent  
current consumption.  
Bias Modes  
The power amplifier may be placed in either a Low Bias  
mode or a High Bias mode by applying the appropriate
