    • PURPOSE: A SAW(Surface Acoustic Wave) resonator, a SAW oscillator, and an electronic apparatus are provided to improve the reliability and quality of a system by improving frequency temperature characteristics, jitter characteristics, and phase noise characteristics. CONSTITUTION: A SAW(Surface Acoustic Wave) resonator(110) includes a quartz substrate(30), an IDT(Inter Digital Transducer)(112) formed on the quartz substrate, and a reflector(120) formed on both sides of the IDT. The IDT is perpendicularity extended in a radio direction of a SAW. A first comb-shaped electrode(114a) is composed of a plurality of electrode fingers(118a) arranged at an equal space in the radio direction of the SAW and a bus bar(116a) parallely connecting the plurality of electrode fingers. A second comb-shaped electrode(114b) is composed of a plurality of electrode fingers(118b) arranged at the equal space in the radio direction of the SAW and a bus bar(116b) parallely connecting the plurality of electrode fingers. The reflector has a conductive strip(122) arranged at the equal space in the radio direction of the SAW.
    • 目的:提供SAW(表面声波)谐振器,SAW振荡器和电子设备,通过提高频率温度特性,抖动特性和相位噪声特性来提高系统的可靠性和质量。 构成:SAW(表面声波)谐振器(110)包括石英衬底(30),形成在石英衬底上的IDT(数字间传感器)(112)和形成在IDT两侧的反射器(120) 。 IDT在SAW的无线电方向上是垂直的。 第一梳状电极(114a)由布置在SAW的无线电方向上的等间距的多个电极指(118a)和平行连接多个电极指的母线(116a)组成。 第二梳状电极(114b)由布置在SAW的无线电方向上的等间隔处的多个电极指(118b)和平行连接多个电极指的母线(116b)组成。 反射器具有布置在SAW的无线电方向上的相等空间处的导电条(122)。
