Abstract: Disclosed is a method comprising obtaining a plurality of signals for transmission, wherein the signals are digital signals, determining individual values for the plurality of signals, respectively, wherein at least two of the individual values are different from each other, adding the individual values to the plurality of signals, respectively, performing a digital to analog conversion, individually, to the plurality of signals by their respective digital to analog converters, removing, from the plurality of signals, the individual values that were added to the individual signals, and transmitting the plurality of signal using a plurality of antennas.

Abstract: Aspects and embodiments provide a transceiver comprising: a transmit signal path; a receive signal path; bidirectional amplification circuitry reconfigurable for use in both the transmit signal path or receive signal path. The amplification circuitry includes at least one resonant tunnelling diode; and the control circuitry is configured to selectively couple the amplification circuitry into the transmit or receive path of the transceiver in dependence upon whether the transceiver is to operate to transmit or receive a signal. The compact and energy efficient transceiver system in accordance with aspects and embodiments recognises that the physical properties of resonant tunnelling diodes provide a mechanism for simplification of transceiver circuitry and may enable transceiver arrangements which can operate in the high mm-wave and terahertz frequency ranges.
