Abstract:
Disclosed is a package having a thin film bulk acoustic resonator (FBAR). The package may be utilized for suppressing spurious resonance occurred during operation of the FBAR. The package includes a negative impedance converter (NIC) operatively coupled to the FBAR through at least one interconnect. The at least one interconnect includes transmission lines and bonding wires. The package further includes a filter operatively coupled to the NIC. The filter exhibits a parallel resonance at a predefined frequency. The parallel resonance exhibited by the filter is converted to a series resonance by the NIC such that the series resonance of the NIC is responsible for suppressing the spurious resonance occurring during the operation of the FBAR.
