Application Circuit

Bias-up Procedure

Bias-down Procedure

1. Set ID limit to 1000 mA, IG limit to 12 mA

1. Turn off RF signal

2. Self-biased mode: Set VG to 0 V

2. Set VD to 0 V. Ensure IDQ ~ 0 mA

Gate-control mode: Adjust VG to obtain desired IDQ

3. Turn off VD supply

3. Increase VD to +6 V

4. Turn off VG, VSW supply

4. Apply RF signal
