Oscillation frequency of a GaN-based surface acoustic wave delay-line oscillator is investigated in the temperature range from -20°C to +38°C, with and without UV illumination. The results imply that such an oscillator may be used for temperature sensing with the resolution of up to 1 mK. On the other hand, as the frequency downshift due to UV illumination does not exhibit a significant dependence on temperature, it may be expected that such a system, when used as a UV sensor, would not require applying a correction for temperature.
