Description

A leaky surface acoustic wave on 0-15°YX-LiNbO_3 has a large electro-mecahnical coupling factor, but it has a leaky component. In order to change to Love wave without its leaky component, Au or Cu electrode with a low velocity has been used. It was reported that a resonator composed of a Cu-electrode/15°YX-LiNbO_3 had wide bandwidth of 12%. This time, authors attempted to fabricate an one-port resonator composed of a grooved Cu-electrode/4°YX-LiNbO_3. As the result, it had a wider bandwidth of 17% of 1.3 times and higher resonant and anti-resonant frequencies of 1.3 times than that on Cu electrode on 4°YX-LiNbO_3. This resonator was applied to a tunable filter, and the tunable filters having tunable range of 7% in center frequency was realized.
