Abstract
A repeater includes a first coupler that receives a guided electromagnetic wave that propagates along a surface of a transmission medium without requiring an electrical return path, the first coupler generating a received signal in response to the guided electromagnetic wave. A controllable isolator is coupled to the transmission medium between the first coupler and a second coupler. The controllable isolator responds to a control signal by: attenuating a residual portion of the guided electromagnetic wave before reaching the second coupler, when the control signal indicates a repeater mode of operation and passing the residual portion of the guided electromagnetic wave to the second coupler, when the control signal indicates a bypass mode of operation. Repeater circuitry includes processing circuitry configured to generate the control signal and transceiver circuitry configured to generate a transmit signal based on the received signal in the repeater mode of operation.
