摘要： A filter module supporting a carrier aggregation (CA) and an electronic device including the same. The electronic device supporting a carrier aggregation may include one or more antennas and a first filter module configured to send or receive signals to and from the first antenna of the one or more antennas. The first filter module may include one or more filter units configured to include a triplexer for transmitting signals having different frequency bands and one or more amplifiers connected to the filter unit and configured to amplify the sent or received signals. Accordingly, according to an embodiment of the present invention, the design process can be more simplified and a cost for implementing a carrier aggregation can be reduced because the carrier aggregation is implemented without a quadplexer.

摘要： A mixer unit (30) for frequency translating, based on an LO signal, an input signal having one or more input signal components is disclosed. The mixer unit has a signal processing path (50a-d, 60a-d) from each Input terminal (32+, 32−) to each output terminal (34_I+, 34_I−, 34_Q+,34_Q−) of the mixer unit (30), The LO signal has an associated LO signal component (LO_Ia-d, LO_Qa-d) for each signal processing path. The mixer unit (30) comprises a plurality of mixer switches (70a-N) and a control unit (90). The control unit (90) is adapted to, for each signal processing path (50a-d, 60a-d), dynamically select an associated subset, in the following denoted active switch subset, of the plurality of mixer switches (70a-N) for operation in the signal processing path (50a-d, 60a˜d) such that which of the plurality of mixer switches (70a-N) belong to said active switch subset varies in time. At any instant in time, the union of all the active switch subsets is a strict subset, denoted combined active subset, of the plurality of mixer switches (70a-N). The control unit (90) is further adapted to activate only the mixer switches (70a-N) in said combined active subset by, for each mixer switch (70a-N) in the combined active subset, supplying the corresponding LO signal component to the mixer switch. A related radio receiver circuit (10), a related radio communication apparatus (1, 2), and a related method are also disclosed.
