Abstract
This paper describes an electrically tunable and switchable film bulk acoustic resonator (FBAR) that is formed by integrating FBAR with an electrostatic MEMS actuator. Around ∼0.8% tuning of the series resonant frequency (Δf ≅18MHz) at 2.3 GHz is experimentally obtained with an electrostatic actuation voltage varying between 12.2 and 27.5V. Also, switchable resonator with Q (quality) factor of greater than 100 at 2.2 and 4.0 GHz is experimentally demonstrated in a compact device area.
