CASCADED COUPLED RESONATOR FILTER SYSTEMS AND METHODS OF OPERATING THE SAME

原文（中国語）

An acoustic wave filter having a coupled resonator filter is provided. The acoustic wave filter includes an acoustic coupling unit, a first unit of resonators disposed on a first side of the acoustic coupling unit, and a second unit of resonators disposed on a second side, opposite the first side, of the acoustic coupling unit. The first unit of resonators and the second unit of resonators are in an acoustic communication. The first unit of resonators includes a first resonator and a second resonator electrically coupled to the first resonator. The first resonator comprises a first electrode and a second electrode, and wherein the second electrode of the first resonator is disposed adjacent to the acoustic coupling unit and is configured to receive a signal input. A wireless device may include the acoustic wave filter.
