A 64GHz full-duplex transceiver front-end with an on-chip multifeed self-interference-canceling antenna and an all-passive canceler supporting 4Gb/s modulation in one antenna footprint
(2018)2018 IEEE International Solid-State Circuits Conference (ISSCC)Millimeter-wave full-duplex (FD) transceivers (TRXs) have the potential to unlock the full throughput of future 5G links. A major challenge in mm-wave FD TRXs is to suppress the wideband modulated self-interference (SI) of the transmitter (TX) to its own receiver (RX) with ~100dB cancellation over a large instantaneous bandwidth. This often requires distributed cancellations across the antenna, RF, and digital domains [1].Other Conference Item
