20-40GHz High Gain Buffer Amplifier
Typical Bias Tuning
The circuit schematic is given below :
For typical operation, the three drain biases are connected altogether. In a same way, all the gate
biases are connected together at the same power supply, tuned to drive a small signal operating
current of 130mA. A separate access to the gate voltages of each stage ( Vg1,2&3 ) is provided for
the fine tuning of the stages regarding the application.
