Does anyone know what filter/circuit the F-35 "dual resonator" modes are meant to emulate?

The XFX multimode filter F-35 has 3 modes called “dual resonator”, and based on tests with a frequency analyzer it looks like they’re basically a dual resonant band pass, with the resonance knob affecting the 3 modes in different ways. Were these modes modeled after a specific filter or filter circuit in the real world?

There are so many different filter types in there that it’s difficult to imagine they are based on “real” analog circuits, but I guess it’s possible. This is definitely a high quality plugin.
