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.
