Embodiments of the present disclosure may relate to a transceiver to transmit and receive concurrently radio frequency (RF) signals via a dielectric waveguide. In embodiments, the transceiver may include a transmitter to transmit to a paired transceiver a channelized radio frequency (RF) transmit signal via the dielectric waveguide. A receiver may receive from the paired transceiver a channelized RF receive signal via the dielectric waveguide. In embodiments, the channelized RF receive signal may include an echo of the channelized RF transmit signal. The transceiver may further include an echo suppression circuit to suppress from the channelized RF receive signal the echo of the channelized RF transmit signal. In some embodiments, the channelized RF transmit signal and the channelized RF receive signal may be within a frequency range of approximately 30 gigahertz (GHz) to approximately 1 terahertz (THz), and the transceiver may provide full-duplex millimeter-wave communication.
