A multi-port reconfigurable coupler includes a coupler and a switching system configured to selectively reconfigure multiple ports of the coupler for increased application flexibility and for efficiently transmitting and receiving radio-frequency signals. The multi-port reconfigurable coupler includes a transmit signal port, a termination port, a receive signal port, an antenna port, and a switching system configured to selectively couple the termination port to a predetermined termination potential based on information indicating one of a transmit only mode, and a receive only mode, and to decouple based on information indicating a transmit-receive mode.
