    摘要: An acoustic wave filter having excellent steepness is provided without adding any exterior components or any new manufacturing steps. A plurality of filters (10-1) each having a first resonator (2a-1) placed in a serial arm and having a resonance frequency frs and an anti-resonance frequency fas, and a second resonator (4a-1) placed in a parallel arm and having a resonance frequency frp and an anti-resonance frequency fap are provided on a same substrate, where the resonance frequency frs of the first resonator is higher than the resonance frequency frp of the second resonator; the anti-resonance frequency fas of the first resonator is higher than the anti-resonance frequency fap of the second resonator; and the filters (10-1) are connected in multiple stages. At least one of the filters (10-1) connected in multiple stages has a third resonator (6-1) having a resonance frequency frp and an anti-resonance frequency fap. The third resonator (6-1) is formed on the substrate and connected to the serial arm in parallel with respect to the first resonator (2a-1).

    摘要: A method of manufacturing an elastic wave device is provided with a lamination step of forming, on a substrate (1), a plurality of elastic wave devices, each of which includes a lower electrode (2), a piezoelectric film (3), and an upper electrode (4); a measuring step for measuring the operation frequency distribution of the elastic wave devices on the substrate (1); and an adjusting step for forming an adjusting region, in which the thickness of the elastic wave device is different from the thicknesses of other portions in a resonance portion of each elastic wave device, corresponding with the distribution of the operation frequencies. The adjusting region is formed so that the size of the area of the adjusting region of the resonator portion of each elastic wave device is different in accordance with the operation frequency distribution that is measured. Thus, the frequency characteristics of the elastic wave devices are easily adjusted by a small number of steps.
