    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).

With the structure, the dissipation of the vibrational energy to the substrate from the resonance portion can be suppressed, thereby improving the quality factor.

    摘要： A filter has a plurality of piezoelectric thin film resonators formed by sandwiching a piezoelectric film with a lower electrode disposed on a substrate and an upper electrode. Each of the piezoelectric thin film resonators has an electrode region formed with the upper electrode and the lower electrode overlapping each other, whose outline includes a curve. Among the plural piezoelectric thin film resonators, the piezoelectric thin film resonators in the opposing electrode regions of the adjacent piezoelectric thin film resonators are shaped to have outlines complementary to each other. With the filter, influences caused by transverse mode undesired wave of the piezoelectric thin film resonators can be suppressed. Therefore, miniaturization can be achieved without sacrificing the mechanical strength of electrodes having hollow structures.
