Surface acoustic wave (SAW) resonators were deposited on (0°, 138.5°, ψ) LGS (langasite, La3Ga5SiO14) cuts with different Euler angles ψ in this paper. The temperaturedependent characteristics of these SAW resonators were investigated systematically. At room temperature, the (0°, 138.5°, 26.6°) LGS cut has the maximum SAW velocity of about 2716 m/s. The (0°, 138.5°, 3.4°) LGS cut has the minimum SAW velocity of about 2377 m/s. The first-order and second-order temperature coefficients of frequency in the (0°, 138.5°, 26.6°) and (0°, 138.5°, 33.4°) LGS cuts are nearest to zero. The turnover temperature decreases first when the angle ψ varies from 3.4° to 26.6° and increases with the further increase of ψ. The results in this paper may help us design LGS SAW temperature sensors and other types of sensors.
