There's no source or load resistor, so it cannot be said to be a filter as such. It's just a bunch of reactances sticking around. There's no source or load to define a filter coefficient on.
Whenever you're doing something with RF (and in fact, this generalizes to everything, not just RF), you must have loss resistance, somewhere. Loss means work performed. Usually as heat. But it also means work generated, which is why sources always have resistance. It also means the potential for more work being done, as an amplifier has input and output impedances: the amplifier's input needs to be matched, in order to maximize gain, and therefore available work at its output!
Also, since this appears to be LTspice, beware of the default loss values given (which are not shown on the schematic by default either
), which may be completely unsuitable to your circuit.
