Temperature control circuit for surface acoustic wave (SAW) resonators

Surface Acoustic Wave (SAW) resonators are key components in oscillators, frequency synthesizers and transceivers. One of the drawbacks of a SAW resonator is that its piezoelectric substrate is highly sensitive to ambient temperatures which results in performance degradation. This work proposes a s...

description Surface Acoustic Wave (SAW) resonators are key components in oscillators, frequency synthesizers and transceivers.
