Patent ID: 7592885

Claim:
A stacked dielectric band-pass filter, comprising: a stacked dielectric block in an approximately rectangular shape, input terminals and output terminals formed on one pair of side faces opposed to each other of the stacked dielectric block, and ground terminals formed on the other pair of side faces opposed to each other of the stacked dielectric block; the stacked dielectric block further comprising: a pair of first λ/4 resonator electrodes that are formed on approximately the same plane, and connected to the input terminals or the output terminals via lead conductors respectively, two capacitance electrodes that are opposed to the first λ/4 resonator electrodes via a first dielectric layer respectively, and formed on approximately the same plane, and a λ/2 resonator electrode connecting the capacitance electrodes, and a pair of second λ/4 resonator electrodes that are opposed to the capacitance electrodes via a second dielectric layer respectively, formed on approximately the same plane, and buried in layers.
