摘要： A laminated filter comprising a plurality of resonator electrodes, an inter-resonator coupling capacitor electrode for coupling adjacent resonators, and two input/output coupling capacitor electrodes for coupling input/output terminals and the resonator electrodes. This provides a capacitor electrode for electrically connecting one side of the input/output terminals with a portion of the input/output coupling capacitor electrode, wherein the input/output coupling capacitor electrode and the capacitor electrode are a parallel circuit. This structure forms a parallel resonance circuit in the input/output terminal, to provide an additional attenuation pole besides an attenuation pole formed by electromagnetic coupling between the resonators and an inter-resonator capacitance, thereby realizing a laminated filter of a high attenuation. With this structure, a duplexer can be made using a plurality of the filters of this invention without requiring a phase-shifting circuit.

摘要： A SAW filter comprising a piezoelectric substrate and at least two filter tracks formed on the substrate, each having at least two IDT electrodes for input and output. The two filter tracks have substantially the same phase within a pass band, while it is substantially inverse-phased outside the pass band. For realizing the above-described conditions, input IDT electrode of one filter track is connected in parallel with input IDT electrode of the other filter track, while output IDT electrode of one filter track is connected in parallel with output IDT electrode of the other filter track. Furthermore, frequency values of said two filter tracks substantially coincide at a point 3 dB lower from the peak transfer function value. Thus the above-configured SAW filter of the present invention is smaller in the overall size and offers a broad pass band and a steep attenuation characteristic.
