1. A radio-frequency circuit comprising:
a plurality of nodes;
a common node; and
a signal path implemented between each of the plurality of nodes and the common node, each signal path including a filter having a first Q-factor value and a resonator having a second Q-factor value higher than the first Q-factor value, the plurality of signal paths configured to support carrier aggregation of respective signals through the common node.
