A Voltage-Controlled Surface Acoustic Wave Oscillator based on Lithium Niobate on Sapphire Low-Loss Acoustic Delay Line

In this work, we investigate, for the first time, a low-phase noise and wide-tuning range voltage-controlled surface acoustic wave oscillator (VCSO) based on a lithium niobate on sapphire (LNOS) low-loss acoustic delay line (ADL). The thin-film LN/SiO
