SAW Resonators

Surface Acoustic Wave (SAW) resonators are electronic components that are used in various applications such as filters, oscillators, and sensors for frequency generation, signal processing, and data transmission. SAW resonators use acoustic waves that propagate on the surface of a piezoelectric substrate, such as quartz, lithium tantalate, or lithium niobate, to generate and filter radio frequency signals.

SAW resonators consist of an interdigitated transducer (IDT) that is fabricated on the surface of the piezoelectric substrate. When an AC voltage is applied to the IDT, it generates surface acoustic waves that propagate along the surface of the substrate. The waves reflect back and forth between two reflecting gratings, creating a resonant cavity with a specific frequency. The resonance frequency is determined by the dimensions and the properties of the substrate and the IDT.

SAW resonators offer several advantages over other types of resonators, such as compact size, low cost, and high performance. They have a high Q-factor, a narrow bandwidth, and a high temperature stability, making them suitable for a wide range of applications that require stable and precise frequency sources or filters.

SAW resonators are widely used in various applications, such as wireless communication systems, digital audio broadcasting, remote sensing, and instrumentation. They come in different sizes and configurations, such as surface-mount or through-hole, depending on the application and the required performance.
