This is a sort of filter. Because the inductor values are missing it is dificult to guess what it does. Maybe it is some harmonics filter, it can have three peaks.
This part is used as antenna of 125khz transceiver. I think that L1, L2, L3 and c4~c10 consist of a resonance circuit. But I don't know if it is right.
what action do c2,c3 and L4,L5 have?
what kind of a driver is the driver. What about the opamp circuit.
These can give some clear clue about the job of the circuit.
Pls give these details.
