This work presents a parallel direct-conversion and double-conversion transceiver to solve the problems of crosstalk and LO pulling in the carrier aggregation scenario. An EVM of -34.9 dB is obtained when the output power of the PA driver is 0.4 dBm. Three aggregated carriers with 80 MHz 256-QAM mod...
