MAGNETIC FEEDTHROUGH CANCELLING SURFACE ACOUSTIC WAVE DEVICE |
| 摘要 |
<p>MAGNETIC FEEDTHROUGH CANCELLING SURFACE ACOUSTIC WAVE DEVICE A surface acoustic wave (SAW) device has an input interdigitated transducer (IDT) and an output IDT. One of the transducers is formed as two loops which are interconnected so that unwanted magnetic feedthrough voltages induced in or by such current loops cancel, while currents producing or produced by the SAW add.</p> |
