22-26GHz High Power Amplifier
CHA5093
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.
