Bias Sequencing GaN

Bias OFF

1. Turn RF off

2. Appliy pinch-off voltage to the gate

3. Turn off drain voltage

4. Turn off gate voltage

Bias ON

1. Ensure RF is turned off

2. Apply pinch-off voltage of –5 V to the gate

3. Apply nominal drain voltage

4. Bias gate to desired quiescent drain current

5. Apply RF

* It is recommended that all pins labelled "N/C" be connected to ground
