Estimating the term…
An RF switching circuit that incorporates a film bulk acoustic resonator (FBAR) device and one or more capacitors that are used to vary the capacitance of the FBAR device to change the frequency range that is blocked by the FBAR device. When the RF switching circuit is in a first switching state, a first set of RF signals in a first frequency range is blocked by the RF switching circuit while RF signals of other frequencies are passed by the RF switching circuit. When the RF switching circuit is in a second switching state, a second set of RF signals in a second frequency range is blocked by the RF switching circuit while RF signals of other frequencies are passed by the RF switching circuit.
An apparatus for selectively blocking radio frequency (RF) signals, the apparatus comprising a first switching state and a second switching state, the apparatus further comprising:
A method for selectively blocking radio frequency (RF) signals from passing from an input of a circuit to an output of the circuit, the method comprising:
