APPLICATION INFORMATION

To ensure proper performance, refer to all related

Application Notes on the ANADIGICS web site:

Shutdown Mode

The power amplifier may be placed in a shutdown

mode by applying logic low levels (see Operating

Ranges table) to the VEN and VMODE voltages.

Bias Modes

The power amplifier may be placed in either Low or

High Bias modes by applying the appropriate logic

level (see Operating Ranges table) to the VMODE pin.

Table 5: Bias Control

The Bias Control table below lists the recommended

modes of operation for various applications.

Two operating modes are recommended to optimize

current consumption. High Bias/High Power operating

mode is for POUT levels > 16 dBm. At about 16 dBm,

the PA could be switched to Low Power Mode.
