摘要： A longitudinally-coupled-resonator-type surface acoustic wave filter includes three interdigital transducers provided on a piezoelectric substrate in the direction in which surface acoustic waves propagate. An interdigital transducer disposed at the approximate center among the three interdigital transducers of the longitudinally-coupled-resonator-type surface acoustic wave filter is divided into two parts substantially symmetrically in the propagation direction of the surface acoustic waves and the two parts are connected to balanced signal terminals, respectively. Left and right interdigital transducers of which the polarities are inverted relative to each other are connected to an unbalanced signal terminal to provide a balanced-to-unbalanced conversion function. A reactance component provided on the piezoelectric substrate, inside a package, or outside the package is connected to either of the balanced signal terminals.

摘要： A surface acoustic wave device in which miniaturization and a flat design implemented, is resistant to a deformation responsive to a pressure of a molten resin in the formation of a mold resin layer, and is less susceptible to a characteristic degradation. In the surface acoustic wave device, an IDT electrode is located on a piezoelectric substrate, and an insulator member is arranged such that a space B surrounding the IDT electrode is provided. For the purpose of reducing the area of the space B, reflectors having weighted portions are arranged on both sides of the IDT electrode. The weighted portions include electrode fingers of the reflectors that become shorter in length as they extend farther away from the IDT electrode. The shape of the space B is reduced accordingly.

摘要： An acoustic wave filter device includes longitudinally coupled resonator-acoustic wave filters having a balanced-unbalanced conversion function, and increases the amount of attenuation in an attenuation band and improves the isolation characteristics when the acoustic wave filter device is used as a reception filter of a duplexer. The acoustic wave filter device includes an unbalanced terminal, first and second balanced terminals, first and second longitudinally coupled resonator-acoustic wave filters that are connected between the unbalanced terminal and the first balanced terminal and between the unbalanced terminal and the second balanced terminal, respectively, a first parallel resonator connected between the first balanced terminal and a ground potential, and a second parallel resonator connected between the second balanced terminal and the ground potential. The electrostatic capacitance of the first parallel resonator is different from the electrostatic capacitance of the second parallel resonator. Among the first parallel resonator and the second parallel resonator, the wavelength of the first parallel resonator having a relatively small electrostatic capacitance is shorter than the wavelength of the second parallel resonator having a relatively large electrostatic capacitance.
