Hi guys,

Does anyone know how to find the insertion loss for resonator circuit using LT SPICE?, What kind of simulation does we need to find the value of IL?. Does the resonator need an amplifier to find the IL?. I already simulate the resonator circuit using AC analysis but I'm not pretty sure about the graph obtained. This is my circuit and the graph obtained using LTSPICE. 1.png
I think maybe I'm missing something with the simulation.

From the report that I read, my graph should be like this 2.png


This is the parameter that I've been working on.

Lx = 0.350
Cx = 199
Rx = 8,95k
Cf = 24.9

And what is the difference between above graph and this graph?. I'm little bit of confuse about this. 3.png
