Abstract
A multilayer band pass filter includes a first LC parallel resonator electrically connected to a first input/output terminal, a second LC parallel resonator electrically connected to a second input/output terminal, and a third LC parallel resonator is magnetically coupled to the first LC parallel resonator. The first LC parallel resonator includes a first inductor. The second LC parallel resonator includes a second inductor. The third LC parallel resonator is magnetically coupled to the second LC parallel resonator. A bypass connects the first inductor and the second inductor to each other.
