Application note

The given DC Bias condition in table or curves are for optimum output power.

To optimize the gain a drain voltage of 5V could be apply. With this biasing point , the

output power at 1dB compression decreases by around 1dBm.

The curves below show typical jig measurements versus drain & gate voltages.
