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.

First claim

1 . A radio-frequency architecture comprising:
a first group of plurality of filters each configured to support a band such that a first frequency range covers the respective plurality of bands; a second group of one or more filters each configured to support a band such that a second frequency range covers the respective one or more bands, each filter of the first group configured to provide an impedance at or near a short circuit impedance for a signal in each band of the second group, each filter of the second group configured to provide an impedance at or near a short circuit impedance for a signal in each band of the first group; and a coupling circuit including a common node and configured to couple the common node to the first group through a first path and to couple the common node to the second group through a second path, the coupling circuit including a resonator such that the impedance provided by each filter of the first group for the signal in each band of the second group results in the signal being sufficiently excluded from the first path, and such that the impedance provided by each filter of the second group for the signal in each band of the first group results in the signal being sufficiently excluded from the second path.

17 . A packaged module comprising:
a packaging substrate configured to receive a plurality of components; and a radio-frequency circuit implemented on the packaging substrate and including a first group of plurality of filters each configured to support a band such that a first frequency range covers the respective plurality of bands, and a second group of one or more filters each configured to support a band such that a second frequency range covers the respective one or more bands, each filter of the first group configured to provide an impedance at or near a short circuit impedance for a signal in each band of the second group, each filter of the second group configured to provide an impedance at or near a short circuit impedance for a signal in each band of the first group, the radio-frequency circuit further including a coupling circuit having a common node and configured to couple the common node to the first group through a first path and to couple the common node to the second group through a second path, the coupling circuit including a resonator such that the impedance provided by each filter of the first group for the signal in each band of the second group results in the signal being sufficiently excluded from the first path, and such that the impedance provided by each filter of the second group for the signal in each band of the first group results in the signal being sufficiently excluded from the second path.

23 . A wireless device comprising:
one or more antennas; a front-end module in communication with the one or more antennas and including a radio-frequency circuit having a first group of plurality of filters each configured to support a band such that a first frequency range covers the respective plurality of bands, and a second group of one or more filters each configured to support a band such that a second frequency range covers the respective one or more bands, each filter of the first group configured to provide an impedance at or near a short circuit impedance for a signal in each band of the second group, each filter of the second group configured to provide an impedance at or near a short circuit impedance for a signal in each band of the first group, the radio-frequency circuit further including a coupling circuit having a common node and configured to couple the common node to the first group through a first path and to couple the common node to the second group through a second path, the coupling circuit including a resonator such that the impedance provided by each filter of the first group for the signal in each band of the second group results in the signal being sufficiently excluded from the first path, and such that the impedance provided by each filter of the second group for the signal in each band of the first group results in the signal being sufficiently excluded from the second path; and a receiver configured to process one or more signals associated with the filters of the first and second groups.
