Abstract
Aspects of this disclosure relate to a parallel hybrid acoustic passive filter. The parallel hybrid acoustic passive filter includes a first sub-filter and a second sub-filter. The first sub-filter includes a first acoustic resonator and a first non-acoustic passive component. The second sub-filter includes a second acoustic resonator and second first non-acoustic passive component. The first sub-filter and the second sub-filter are together arranged to filter a radio frequency signal. The parallel hybrid acoustic filter can be a band pass filter or a band stop filter, for example. Related multiplexers, wireless communication devices, and methods are disclosed.
Claims22
A parallel hybrid acoustic passive filter comprising:
- a first sub-filter including a first acoustic resonator and a first non-acoustic passive component;
- and
- a second sub-filter coupled in parallel with the first sub-filter, the second sub-filter including a second acoustic resonator and a second non-acoustic passive component, and the first sub-filter and the second sub-filter are together arranged to filter a radio frequency signal.
A multiplexer with a parallel hybrid acoustic passive filter, the multiplexer comprising:
- a first filter coupled to a common node and configured to filter a radio frequency signal, the first filter including a first sub-filter in parallel with a second sub-filter, the first sub-filter including a first acoustic resonator and a first non-acoustic passive component, and the second sub-filter including a second acoustic resonator and a second non-acoustic passive component;
- and
- a second filter coupled to the common node.
A wireless communication device comprising:
- a radio frequency front end including a filter configured to filter a radio frequency signal, the filter including a first sub-filter in parallel with a second sub-filter, the first sub-filter including a first acoustic resonator and a first non-acoustic passive component, and the second sub-filter including a second acoustic resonator and a second non-acoustic passive component;
- and
- an antenna in communication with the radio frequency front end.
