Abstract :
Temperature dependent scattering parameter data was collected on a 30 × 30 µm2 voltage activated barium strontium titanate solidly mounted resonator. The frequency variation over the temperature range of −40°C to 120°C normalized to room temperature was as low as 0.41% and as high as 0.84%. The resonant frequency measurements also show a step at −10°C which is believed to be a structural phase transition of the ferroelectric material. The data was collected at a dc bias voltage range of 0V to 30V in 5V increments.
