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