Abstract
A stacked dielectric band-pass filter is disclosed, which enables widening of a passband to a side of a high band of 8 GHz or more. Within a stacked dielectric block, a pair of first λ/4 resonator electrodes that are formed on approximately the same plane, and connected to input terminals or output terminals via lead conductors respectively, two capacitance electrodes that are opposed to the first λ/4 resonator electrodes via a dielectric respectively, and formed on approximately the same plane, a λ/2 resonator electrode for connecting the capacitance electrodes to each other, and a pair of second λ/4 resonator electrodes that are opposed to the capacitance electrodes via a dielectric respectively, and formed on approximately the same plane, are buried.
