| titleOfInvention | Tunable bulk acoustic resonator device with improved insertion loss |
| abstract | A tunable BAW filter device operating in an allocated channel of a predetermined frequency band includes a voltage source and multiple BAW resonators. The voltage source selectively provides non-zero DC bias voltage based on a location of the allocated channel within the frequency band. Each BAW resonator has a resonance frequency, and includes a bottom electrode, a piezoelectric layer and a top electrode disposed over the piezoelectric layer, the top electrode being electrically connected to the voltage source via a resistor. The voltage source is activated, applying the non-zero DC bias voltage to the top electrode of each BAW resonator, when the location of the allocated channel is near an upper or lower corner of the frequency band. The resonance frequency of each BAW resonator is shifted in response to the non-zero DC bias voltage toward a center of the frequency band, improving insertion loss of the BAW filter device. |
