Description
Gate control for amplifier. Adjust to achieve Id of 310 mA.
Please follow “MMIC Amplifier Biasing Procedure”
Application Note. External bypass capacitors of 100 pF,
1000 pF and 2.2 μF are required.
No connection required. These pins may be connected to
RF/DC ground without affecting performance.
Package bottom has an exposed metal paddle that must
also be connected to RF/DC ground.
This pin is AC coupled and matched to 50 Ohms.
