Thin-film bulk-acoustic-wave resonators (TFR) and TFR-based filters have been used in single-line-spectra UHF and L-band oscillators in both hybrid and monolithic integrated versions. Two methods are proposed for modeling the behavior of the amplifier in a SPICE simulation. The first uses a nonlinear controlled generator derived from measured gain compression data. The second involves a circuit model of the amplifier used in a closed-loop simulation. The method of deriving the amplifier models is presented along with experimental results for the actual oscillator circuits. The oscillators, using commercial hybrid Darlington amplifiers as the gain element, are evaluated with fundamental mode frequencies in the area of 1 GHz.
