This work presents a reconfigurable 24–28GHz time-division (TD) full-duplex (FD) transceiver in 65nm CMOS. It supports at least 400MHz bandwidth with up to 59dB self-interference (SI) rejection, achieved by isolating TX/RX in time domain without an extra SI cancellation (SIC) path. The proposed architecture overcomes SIC bandwidth limits and allows switching to half-duplex (HD). The OTA measurements verify 400MHz 64QAM OFDM FD and HD operations, offering a low-complexity mm-Wave FD solution.
