Abstract
A filter circuit may include a first path having a first complex baseband filter. The circuit may further include a second path having a second complex baseband filter. The circuit may further include a combiner coupled to an output of the first complex baseband filter and an output of the second complex baseband filter.
Claims22
A filter circuit, comprising:
- a first path including a first complex baseband filter and a set of multiplexers;
- a second path including a second complex baseband filter, the set of multiplexers selectively coupled to an input of the first complex baseband filter and an input of the second complex baseband filter;
- and
- a combiner coupled to an output of the first complex baseband filter and an output of the second complex baseband filter, the combiner configured to combine a first component carrier, of a carrier aggregation signal, from the first path and a second component carrier, of the carrier aggregation signal, from the second path.
