Saw resonator with resonant cavities |
| abstract |
A surface acoustic wave (SAW) resonator is provided with reduced rattling at frequencies lower than the resonance value. The SAW resonator includes an interdigital transducer (IDT) on a piezoelectric substrate. The IDT includes a first set of interdigital electrodes distributed between and parallel to the first end of the n IDT and the second end of the IDT and a second set of interdigital electrodes interleaved with the first plurality of interdigital electrodes. A first resonant cavity is formed a predetermined distance from the first end of the IDT, and a second resonant cavity is formed a predetermined distance from the second end of the IDT. Additionally, a radio frequency (RF) filter is provided that includes multiple n SAW resonators that include the resonant cavities formed a predetermined distance from the first and second ends of the IDT. This RF filter may provide increased bandwidth and reduced insertion loss. |
