  • Resonator, and filter and duplexer using the same
    Patent number: 11799446
    Abstract: A resonator includes an interdigital transducer provided with a main electrode area formed to a shape of a comb on a piezoelectric substrate by a reference pitch in such a manner as to have a unit length along a longitudinal direction thereof and one pair of first electrode areas constituted of one side first electrode area formed to a shape of a comb on the piezoelectric substrate by a first increment pitch obtained by increasing the reference pitch by a first value in such a manner as to have the unit length along the longitudinal direction and the other side first electrode area formed to a shape of a comb on the piezoelectric substrate by a first decrement pitch obtained by decreasing the reference pitch by almost the same value as the first value.
