  • Publication number: 20250253872
    Abstract: A radio-frequency architecture can include a first circuit configured to support a first frequency range, and a second circuit configured to support a second frequency range. The first circuit can be further configured to provide an impedance at or near a short circuit impedance for a signal in the second frequency range, the second circuit can be further configured to provide an impedance at or near a short circuit impedance for a signal in the first frequency range. The architecture can further include a coupling circuit having a common node and configured to couple the common node to the first circuit and to couple the common node to the second circuit. The coupling circuit can include a resonator such that the signal in the second frequency range is sufficiently excluded from the first circuit, and the signal in the first frequency range is sufficiently excluded from the second circuit.

  • Patent number: 12302538
    Abstract: A converter module, including a housing and a converter body mounted within the housing. The housing and the converter body are joined to form a cooling channel. A fan is mounted in the cooling channel. An air inlet and an air outlet in communication with the cooling channel are provided on the housing. The cooling channel is distributed at two sides of the converter body. In the converter module described above, the housing and the converter body are joined to form the cooling channel, and the cooling channel at least is distributed at either side of the converter body, thus allowing a cooling airflow to cool the converter body from either side, favoring the implementation of even cooling, and increasing the cooling effect.

    Abstract: Aspects of this disclosure relate to a multiplexer with an acoustic assisted trap circuit. The multiplexer includes an acoustic wave filter with an acoustic wave resonator and an impedance network that together provide a trap for a harmonic associated with another acoustic wave filter of the multiplexer. The acoustic wave filter can have an edge of a passband that is farther from the harmonic than other acoustic filters of the multiplexer.

  • Patent number: 12191894
    Abstract: Bride combiners with resonators for radio-frequency applications. A bridge combiner can be implemented as a coupling circuit that includes 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 include a resonator 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.
