Typical Bias Tuning
The circuit schematic is given below :
18-32GHz Low Noise Amplifier
Vd 1,2,3
IN
OUT
Vg 1
Vg 2,3
The three drain biases are connected altogether on chip. For typical operation, all the gate
biases are connected together at the same power supply, tuned to drive a small signal
operating current of 60 mA. A separate access to the gate voltages of the first stage ( Vg1 )
and the second and third stages ( Vgs2,3 ) is provided for the fine tuning of the amplifier
regarding the application.
