Abstract
A block downconversion receiver incorporates a digital image rejection technique to support multiple aggregated carriers by one receive path and one frequency synthesizer. A prototype consisting of a CMOS RF front end and an FPGA back end exhibits an image rejection ratio (IRR) of at least 70 dB across 2 GHz ± 25 MHz and reconstructs a -76-dBm 64-QAM signal with an EVM of -30 dB in the presence of another channel 40 dB higher.
