Broadband, high frequency, thin film piezoelectric transducers |
| abstract |
Piezoelectric thin film transducers are provided in a form to match the impedance of a transmission line. The transducer structure includes a plurality of serially connected transducer elements on a single substrate provided by a first pattern of electrodes on the substrate, a single layer of piezoelectric material overlying the first electrode pattern and a second electrode pattern overlying the piezoelectric layer with selective connections between electrodes of the first and second patterns, such structure being directly amenable to fabrication by thin film technology. Such an arrangement provides greatly increased bandwidth characteristics and improved conversion efficiency. |
