该论文提出了一种64GHz全双工收发机前端，采用片上多馈自干扰消除天线和全通网络，解决了毫米波全双工系统中宽带调制自干扰抑制的难题。通过天线域、射频域和数字域的分布式抵消，实现了约100dB的自干扰消除，显著降低了接收机线性度要求。
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]. The antenna-domain self-interference cancellation (SIC) is critical since it directly relaxes the RX linearity requirement [1]. Practical antenna SIC solutions should provide low loss, compact footprint, and a large modulation bandwidth. Several antenna-interface SIC techniques have been demonstrated in silicon, each with advantages/limitations for wideband high mm-wave applications. First, reciprocal electrical-balance duplexers [2] suffer from 3dB signal loss, directly degrading
