Cascaded filter circuit with hybrid acoustic LC filter

Abstract:

Aspects of this disclosure relate to a cascaded filter circuit that includes a hybrid acoustic LC filter, a non-acoustic LC filter, and a switch configured to selectively couple the hybrid acoustic LC filter and the non-acoustic LC filter. The hybrid acoustic filter can filter a radio frequency signal. The hybrid acoustic LC filter can include an acoustic resonator, an inductor, and a capacitor. The non-acoustic LC filter includes an LC circuit. Related multiplexers, wireless communication devices, and methods are disclosed.
