  • Publication number: 20180302060
    Abstract: In order to suppress an interference frequency in a ladder-type filter, an additional resonator (RZ1) that acts as a capacitance is connected in parallel to a series resonator (S1). The antiresonance of the additional resonator creates an additional pole in order for the interference frequency to be attenuated more effectively.
