  • Patent number: 11323097
    Abstract: Bulk acoustic wave resonators of two or more different filters can be on a common die. The two filters can be included in a multiplexer, such as a duplexer, or implemented as standalone filters. With bulk acoustic wave resonators of two or more filters on the same die, the filters can be implemented in less physical space compared to implementing the same filters of different die. Related methods, radio frequency systems, radio frequency modules, and wireless communication devices are also disclosed.

  • Patent number: 11271602
    Abstract: A receiving system includes a controller that selectively activates one or more of a plurality of paths between an input of a first multiplexer and an output of a second multiplexer. The receiving system includes a plurality of bandpass filters, each one of the bandpass filters being disposed along a corresponding one of the plurality of paths and configured to filter a signal received at the bandpass filter to a respective frequency band. The receiving system also includes a plurality of variable-gain amplifiers (VGAs), each one of the plurality of VGAs disposed along a corresponding one of the plurality of paths and configured to amplify a signal received at the VGA with a gain controlled by an amplifier control signal received from the controller. At least one, but not all, of the VGAs is a fixed-gain amplifier with a bypass switch to selectively bypass the fixed-gain amplifier.

    Abstract: Described herein are systems, devices, and methods for front end configurations that support multiple input multiple output (MiMo) communication for cellular signals. The configurations include an antenna triplexer, a first multiplexer, and a second multiplexer. A first filter of the triplexer is coupled to a signal port of the first multiplexer, a second filter of the triplexer is coupled to a first signal port of the second multiplexer, and a third filter of the triplexer is coupled to a second signal port of the second multiplexer. The first multiplexer processes low-band (LB) cellular frequency bands and the second multiplexer processes mid-band (MB), high-band (HB), and ultra high-band (UHB) cellular frequency bands. Each frequency band includes a duplexer to enable bi-directional communication.

  • Patent number: 11190223
    Abstract: Described herein are systems configured for carrier aggregation. Systems include a multiplexing circuit having a filter assembly, switching circuit with a switching path, and a switchable impedance. The filters can be designed so that when operated simultaneously (e.g., during multi-band operation) the same inductance can be used allowing the switching network to switch in a particular inductance into the path. The described systems can include an inductance that is coupled to an output port so that when operating in single-band mode, the different paths share the same inductance. Relative to other solutions, the described systems can improve performance (e.g., reduce insertion loss), reduce the number of components in the associated module, reduce manufacturing costs, and the like.

    Abstract: A switching circuit can be provided for a coupling circuit having a common node and configured to couple the common node to a first group of filters through a first path and to couple the common node to a second group of one or more filters through a second path. The coupling circuit can be further configured such that an impedance provided by each filter of the first group for a signal in each band of the second group results in the signal being sufficiently excluded from the first path, and such that an impedance provided by each filter of the second group for a signal in each band of the first group results in the signal being sufficiently excluded from the second path. The switching circuit can be configured to provide a filter selection functionality along either or both of the first and second paths.

  • Patent number: 11082077
    Abstract: A front-end module (FEM) is disclosed that includes an integrous signal combiner. The integrous signal combiner can process received signals and use a set of resonant circuits to filter signal noise prior to recombination of a plurality of signal bands that form an aggregate carrier signal. These resonant circuits may be placed after a set of low noise amplifiers and can be used to more efficiently reduce noise and parasitic loading within each of a set of signal paths. Each resonant circuit may be configured to filter noise relating to a bandwidth for a signal that is to be combined with the signal of the signal path that includes the resonant circuit. In some implementations, the integrous signal combiner can be a tunable integrous signal combiner with resonant circuits that may be reconfigurable or dynamically configurable.
