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 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
Table 5: Bias Control
logic level (see Operating Ranges table) to the VMODE
voltage. The Bias Control table lists the recommended
modes of operation for various applications.
Three operating modes are recommended to optimize
current consumption. High Bias operating mode is for
POUT levels > 16 dBm. At POUT <16dBm, the PA should
be “Mode Switched” to Low Bias Mode. For POUT levels
< ~7 dBm, the VCC can be switched to 1.5 V (Low Bias
Mode is also used for this POUT range).
