(1) Load impedance for optimum P1dB power. (2) Load impedance for optimum P3dB power.
Zsource = Measured impedance presented to the input of the device at the package reference plane.
Zin = Impedance as measured from gate contact to ground.
Zload = Measured impedance presented to the output of the device at the package reference plane.
