Abstract
Filter combinations for carrier aggregation. In some embodiments, a carrier aggregation circuit can include a first combining stage configured to aggregate a first signal in a first path associated with a first band and a second signal in a second path associated with a second band to provide a first aggregated signal in a first combined path. The carrier aggregation circuit can further include a second combining stage configured to aggregate the first aggregated signal in the first combined path and a third signal in a third path associated with a third band to provide a second aggregated signal in a second combined path.

A method for aggregating radio-frequency signals, the method comprising:
- combining a first signal in a first path associated with a first band and a second signal in a second path associated with a second band to provide a first aggregated signal in a first combined path;
- and
- combining the first aggregated signal in the first combined path and a third signal in a third path associated with a third band to provide a second aggregated signal in a second combined path.
A method for operating a radio-frequency device, the method comprising:
- providing a front-end circuit in communication with an antenna;
- and
- operating the front-end circuit to include combining a first signal in a first path associated with a first band and a second signal in a second path associated with a second band to provide a first aggregated signal in a first combined path, and combining the first aggregated signal in the first combined path and a third signal in a third path associated with a third band to provide a second aggregated signal in a second combined path.
