RADIO RECEIVER FOR CARRIER AGGREGATION

摘要

A radio receiver circuit (10) configurable to operate in a carrier-aggregation, CA, mode and in a non-CA mode is disclosed. It comprises a first receive path (30) arranged to be operatively connected to an antenna (15) and a second receive path (40) arranged to be operatively connected to the same antenna (15). It further comprises a control unit (50) operatively connected to the first receive path (30) and the second receive path (40). In the CA mode, the control unit (50) controls the first receive path (30) to receive a first CC (6) and the second receive path to receive a second CC (8). In the non-CA mode, the control unit (50) selectively controls the first receive path (30) and the second receive path (40) to both receive the same single CC (6).
