Abstract
A device can include a thin-film bulk acoustic resonator (“FBAR”), a transceiver, a capacitor network, and a processor. The transceiver can transmit and receive radio frequency (“RF”) signals using the FBAR. The capacitor network can be conductively coupled to the FBAR. The processor can be in communication with the capacitor network. The processor can obtain a capacitor tuning code. The processor can further establish a capacitance of the capacitor network based on the capacitor tuning code during a RF receiving operation.
