    摘要： There is provided a piezoelectric thin film resonator that decreases only transverse mode waves selectively while maintaining resonance characteristics due to original thickness longitudinal vibration. The piezoelectric thin film resonator includes: a piezoelectric film (14); a first electrode (15a) formed on a first principal surface of the piezoelectric film (14); and a second electrode (13) formed on a second principal surface of the piezoelectric film (14) opposite to the first principal surface. The resonator has a resonance region (20) where the first electrode (15a) and the second electrode (13) are opposed to each other. An electrically discontinuous portion (18a) that is insulated from the first electrode (15a) is provided on the first principal surface of the piezoelectric film (14) in the resonance region (20), and the electrically discontinuous portion (18a) is surrounded by the first electrode (15a) on the first principal surface.

    摘要： A filter includes piezoelectric thin-film resonators having a substrate, a lower electrode supported by the substrate, a piezoelectric film provided on the lower electrode, and an upper electrode provided on the piezoelectric film. At least one of the piezoelectric thin-film resonators has a portion in which the upper electrode overlaps the lower electrode across the piezoelectric film. The above portion has a shape different from shapes of corresponding portions of other piezoelectric thin-film resonators, so that a spurious component in the above at least one of the piezoelectric thin-film resonators occur at a frequency different from frequencies of spurious components that occur in the other piezoelectric thin-film resonators.

    摘要： A duplexer includes an antenna terminal, a first filter connected to the antenna terminal, a second filter that has a passband at a high-frequency side of the first filter and is connected to the antenna terminal, and a resonance circuit that is connected between the second filter and the antenna terminal and includes a first inductor and a first capacitor connected in parallel. Assuming that a passband frequency of the first filter ranges from f1Low to f1High (f1Low˜f1High) and a passband frequency ranges from f2Low to f2High (f2Low˜f2High), the resonator has a resonance frequency fr satisfying: fr=(f2Low˜f2High)±(f1Low˜f1High), or fr=2(f1Low˜f1High)±(f2Low˜f2High).
