Adjustable resonator component for mobile telephone, has inductor with quality coefficient having one value in preset frequency range and another value outside range, and capacitor adjusting tuning of resonator on resonance frequency

摘要

The component has a bulk acoustic wave resonator with a resonance frequency and an anti-resonance frequency. An inductor cancels the anti-resonance frequency of the resonator and has one Q-factor in a predetermined frequency range and another value of Q outside the frequency range. A capacitor adjusts the tuning of the resonator on the resonance frequency.
