文摘

Temperature compensated solidly mounted resonators are designed and fabricated. The influence of material properties of the different reflector layers composing the device on the TCF is discussed in detail. TCF is measured in both shear and longitudinal wave mode of the resonant frequency. The affect of temperature compensation on overall performance of SMRs is measured.
