    摘要: Provided are a method and device for manufacturing a film resonator. The manufacturing method includes that: a thickness of each film layer which has been deposited is detected; when the detected thickness of any film layer which has been deposited is not in a standard thickness range, it is judged whether a mass loading layer has been deposited, and when the mass loading layer has not been deposited, at least one film layer which has not been deposited is selected for thickness compensation, and according to a compensated thickness of the selected at least one film layer which has not been deposited and a target frequency offset, a thickness of the mass loading layer required for generating the target frequency offset is calculated, wherein the standard thickness range is determined by a target frequency and a process production capacity of the resonator; subsequent film deposition is conducted according to the compensated thickness of the selected at least one film layer which has not been deposited and the calculated thickness of the mass loading layer. The manufacturing method and device can accurately generate the required frequency offset, thereby improving the yield rate of products.

    摘要: A radio frequency filter system includes a first acoustic resonator (54, 56) for a first frequency and a second acoustic resonator (54, 56) for a second frequency. An acoustic reflector array (102, 152, 202) is coupled to an electrode of the first acoustic resonator (54, 56) and to an electrode of the second acoustic resonator(54, 56). The acoustic reflector array (102, 152, 202) includes a plurality of reflector layers (112, 152, 210). A first reflector layer (112, 152, 210) is operable to reflect a signal at substantially the first frequency. A second reflector layer (112, 152, 210) is operable to reflect a signal at substantially the second frequency.

    摘要: In an array of acoustic resonators, the effective coupling coefficient of first and second filters (68 and 73) are individually tailored in order to achieve desired frequency responses. In a duplexer embodiment, the effective coupling coefficient of a transmit band-pass filter is lower than the effective coupling coefficient of a receive band-pass filter of the same duplexer. In one embodiment, the tailoring of the coefficients is achieved by varying the ratio of the thickness of a piezoelectric layer (94 and 100) to the total thickness of electrode layers (92, 94, 96 and 98). For example, the total thickness of the electrode layers of the transmit filter may be in the range of 1.2 to 2.8 times the total thickness of the electrode layers of the receive filter.

    摘要: A piezoelectric resonator is obtained that is capable of having a reduced size and thickness thereof and that is less prone to having a spurious component occurring in a mode at which it propagates in a piezoelectric thin film at a range higher than a resonant frequency. A piezoelectric resonator includes a laminated thin film having a first thin film portion supported by a substrate 2 and a second thin film portion separated from a first main surface of the substrate and acoustically isolated. The second thin film portion of the laminated thin film includes a piezoelectric thin film 5, a first electrode 12 disposed on the upper surface of the piezoelectric thin film, and a second electrode 13 disposed on the lower surface of the piezoelectric thin film and being larger and thicker than the first electrode. The piezoelectric resonator further includes a mass adding film 11 disposed around the first electrode 12 and on at least one part of a region outside the periphery of a piezoelectric vibrating portion where the first and second electrodes 12 and 13 overlap each other with the piezoelectric thin film 5 disposed therebetween. The second electrode 13 is formed, in plan view, so as to extend beyond the piezoelectric vibrating portion to a region at which the mass adding film 11 is disposed.
