Abstract
A tunable coupled resonator filter (CRF) structure is provided. Herein, the tunable CRF structure includes a ferroelectric input shunt resonator, a ferroelectric series resonator, and a ferroelectric output shunt resonator. The tunable CRF structure also includes a coupling layer that is coupled to the ferroelectric input shunt resonator, the ferroelectric series resonator, and the ferroelectric output shunt resonator. In embodiments disclosed herein, the coupling layer can be tuned by a tuning voltage to modify a parallel resonance frequency of the ferroelectric input shunt resonator and the ferroelectric output shunt resonator. As a result, it is possible to dynamically change the parallel resonance frequency of the tunable CRF structure based on various radio frequency (RF) filtering requirements.
