摘要: A quartz single crystal substrate (12), includes a prescribed range of Euler angles for and orientation which improves signal processing surface acoustic wave (SAW) devices (10). When voltage is applied to an input inter digital transducer (IDT) (16) the SAW device (10), generated in (12). The propagates direction generally perpendicular electrodes (20) IDT (16). cut propagation directions are defined reduce adverse effects diffraction on As result, frequency response distortions insertion loss increases due reduced while maintaining good temperature stability low power flow angle.
