<P>PROBLEM TO BE SOLVED: To provide a surface acoustic wave device which can ensure desired frequency characteristics by making the inductance component adjustable easily without causing increase in cost or development period or deterioration of the characteristics. <P>SOLUTION: The surface acoustic wave device is provided with, in a package 2, a plurality of package side GND electrodes 21, 22, and 23 connectable with a GND electrode 11 of an SAW chip 1 and disposed so that the line lengths from an interdigital electrode 19 are different, and a plurality of package side GND electrodes 24, 25, and 26 connectable with a GND electrode 12 of the SAW chip 1 and disposed so that the line lengths from an interdigital electrode 18 are different. The GND electrodes 11 and 12 of the SAW chip 1 and one or a plurality of corresponding package side GND electrodes are connected by flip-chip bonding so that the inductance between a parallel resonator and a ground level has a desired value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
