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

Table 6: Bias Control

Bias Modes

The power amplifier may be placed in either a Low Bias

mode or a High Bias mode by applying the appropriate

voltages. The Bias Control table lists the recommended

modes of operation for various applications.

Note:

(1) Add blocking cap if DC voltage is present on input pin.

(2) TRL should be short and of 50  characteristic impedance.

(3) TRL 5 should be as long as possible (minimum of 0.1  at 800 MHz) and capable of handling 1200 mA current.
