Abstract:A sub-THz (88-136 GHz) full-duplex (FD) phasedarray transceiver (TRX) integrating an RF self-interference (SI) canceller with differential feeding FD antennas is presented in this work. The LO phase generation chain controls differential transmitter outputs for the phased-array operation. The differential feeding FD antenna with differential pairs of chips achieves over 35-dB SI suppression. The SI suppression is improved by 20 dB when the SI canceller is turned on. Without any digital-domain SI cancellation (… Show more
