Various frequency control devices and their methods of use are provided. In one aspect, a bulk acoustic wave (BAW) device may include a diamond layer disposed between piezoelectric layers, and a pair of electrodes coupled to the piezoelectric layers. In such a configuration, the pair of electrodes may be configured such that an electrical signal introduced across the pair of electrodes can generate an acoustic wave in the diamond layer as a result of movement in the piezoelectric layers. The pair of electrodes may be a pair of electrode layers, and the diamond layer and the two piezoelectric layers may be disposed at least partially therebetween. |
