This definition does not require common circuits:
The term is fairly old and probably dates from WWII or before. In full
duplex operation, a transceiver may not share any common parts except
the box. Combining the functions goes back at least as far as the
Motorola patent which I believe was prior to WWII. The Motorola patent
is for a device for military communications.
