Abstract
A band switching filter includes a resonator circuit having a surface acoustic wave resonator, a switching element and an impedance element. The filter selectively passes or attenuates a signal through one of two pass bands using a single filter. The resonant frequency of the resonator circuit can be shifted to another frequency by selectively connecting the surface acoustic wave resonator to an impedance element using a switching element.
