    摘要: An electronic component includes a substrate; a piezoelectric material layer supported directly or indirectly by the substrate; a first electrode arranged on a surface of the piezoelectric material layer on an opposite side of the substrate; and a second electrode arranged on a surface of the piezoelectric material layer on the substrate side. The piezoelectric material layer is sandwiched between the first electrode and the second electrode. The first electrode has a smaller surface area than the piezoelectric material layer. A portion where the piezoelectric material layer is exposed from the first electrode includes a portion that is thinner than a thickness of the piezoelectric material layer between the first electrode and the second electrode. Thus, it is possible to configure a resonator with a higher frequency than its ordinary resonance, and it is easy to achieve an adjustment of the resonance frequency of the resonator, as well as improving the yield of the component and enabling the configuration of an electronic component that includes a plurality of resonators of different frequencies.

    摘要: Disclosed is a SAW element with a propagation substrate that is a piezoelectric substrate. An auxiliary substrate is laminated on one surface of the propagation substrate by way of direct bonding, and a comb-shaped electrode is formed on another surface of the propagation substrate that is opposite the surface with the auxiliary substrate. The electrode excites an acoustic wave. The propagation substrate and the auxiliary substrate are not bonded to each other in at least a region immediately below a region where the comb-shaped electrode is formed. A coefficient of thermal expansion in a propagation direction of the acoustic wave of the auxiliary substrate is smaller than a coefficient of thermal expansion in a propagation direction of the acoustic wave of the propagation substrate.

    摘要: A synthesizer including an oscillator for outputting an oscillation signal based on an output signal from a comparator, a frequency divider for dividing a frequency of an output signal from the oscillator based on control from a controller, and a temperature sensor for detecting an error between a preset frequency and a frequency based on a reference oscillation signal. The comparator compares an output signal from the frequency divider with an output signal from a MEMS oscillator and outputs a signal indicating the comparison result to the oscillator. The controller changes the frequency division ratio of the frequency divider based on an output signal from the temperature sensor and changes the frequency division ratio in a state in which the frequency division ratio is kept at the past value. Thus, phase noise deterioration in the synthesizer can be suppressed.

    摘要: A synthesizer includes: a synthesizer unit that outputs an oscillation signal based on a reference oscillation signal; a temperature detecting unit that detects a temperature; a time variation detecting unit that detects a time variation in frequency of the reference oscillation signal based on a result of temperature detection by the temperature detecting unit; and a control unit that adjusts a frequency of the oscillation signal outputted from the synthesizer unit based on a result of detection by the time variation detecting unit. With such a configuration, frequency compensation control is performed on a transducer having a large temperature coefficient.
