A new architecture for multi-channel carrier aggregation receivers is proposed for eliminating risks of VCO injection pulling and mitigating performance degradation resulting from Multi-Lomutual coupling. A fully integrated receiver front-end is implemented, enabling the realization of a robust multi-LO triple-carrier-aggregation system operating in the 5.2-5.8 GHz band. The RFIC demonstrates EVM better than 30dB for all three noncontiguous 80MHz channels. It is implemented in 65nm CMOS LP process and occupies a die area of 1mm .
