Zin = Conjugate of source impedance with parallel 39 Ω
Zin = resistor and 47 pF capacitor in series with gate.
ZOL* = Conjugate of the load impedance at given output
ZOL* = power, voltage, frequency, and η_D > 50%.
Note: ZOL* was chosen based on tradeoffs between gain, drain efficiency, and device stability.
