Application Circuit

NOTE 1: Drain Bias (Vdd) must be applied through a broadband bias tee

having low series resistance and capable of providing 1000 mA.

NOTE 2: Optional capacitors to be used if part is operated below 200 MHz.

NOTE 3: Optional capacitors to be used if external VGG2 is applied. Typical operation has VGG2 set

internal to IC. Setting VGG2 to 9.5V externally can improve thermal resistace and will require

capacitors as shown.
