Switchable acoustic wave filter and related multiplexer

Aspects of the present disclosure relate to a switchable acoustic wave filter. The switchable acoustic wave filter may include a switch configured to electrically connect the acoustic wave resonator to the node in a first state and electrically isolate the acoustic wave resonator from the node in a second state. The switchable acoustic wave filter may filter the radio frequency signal with at least the acoustic wave resonator and the second acoustic wave resonator in a first state. The switchable acoustic wave filter may filter the radio frequency signal with at least a second acoustic wave resonator in a second state. Related multiplexers, radio frequency systems, wireless communication devices, and methods are also disclosed. 本公开的方面涉及可切换声波滤波器。可切换声波滤波器可以包括开关，该开关被配置为在第一状态将声波谐振器电连接到节点并且在第二状态将声波谐振器与节点电隔离。可切换声波滤波器可以在第一状态中用至少所述声波谐振器和第二声波谐振器对射频信号进行滤波。可切换声波滤波器可以在第二状态中用至少第二声波谐振器对射频信号进行滤波。还公开了相关的多路复用器、射频系统、无线通信设备、和方法。
