I'm trying to model a frequency-dependent load so I can generate accurate Bode plots using LTspice. The load is characterized by the attached Smith chart and impedance curves as captured using a VNA. Any suggestions?
So, the task is to come up with a passive network that has the same Mag(Z) and Phase(Z) as the right side of the plot? By inspection, it looks to me to be a simple parallel resonant tank with a modest Q?
I would start by just doing freq sweeps of a simple network, where you can use stepped parameters to vary the inductance and/or capacitance.
