Reverse coupler for transceiver devices

Abstract:

An electronic device may include a feedback circuit that may determine an error of a first signal to be transmitted to a second electronic device. The electronic device may also include a transceiver that may adjust the first signal based on the error and send the adjusted first signal to the second electronic device. The electronic device may also include a coupler circuitry configured to route a second signal received from the second electronic device or a third electronic device to the feedback circuit, such that the feedback circuit may determine one or more properties associated with the second signal.
