Abstract
A sub-THz (88–136 GHz) full-duplex (FD) phased-
array 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 differen-
tial 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
