Power-up Sequence:
1) Ground the device.
2) Set Vg1 to -1.5V.
3) Set Vd to 6.5V (nominal value for Vd).
4) Set Vg2 to 1.5V (nominal value for Vg2).
5) Set Vg1 in the range of -0.3V for having Idq=120mA.
6) Apply RF input power and adjust Vg2 to obtain desired gain.

Power-down Sequence:
1) Turn RF power supply off.
2) Set Vg1 to -1.5V in order to get Idq=0mA.
3) Set Vg2 to 0V.
4) Set Vd to 0V.
5) Set Vg1 to 0V.
