Abstract
In accordance with one or more embodiments, an analog surface wave multi-point repeater includes a first launcher configured to transmit and receive first guided electromagnetic waves that propagate on an outer surface of a first segment of a transmission medium without requiring an electrical return path. A transceiver includes a splitter coupled to a second launcher and the third launcher and a low noise amplifier configured to receive a second microwave signal from the second launcher and the third launcher via the splitter. A directional coupler is configured to couple the second microwave signal from the second launcher and the first microwave signal to the splitter to facilitate transmission of the second guided electromagnetic waves by the second launcher on the second segment of the transmission medium and to further facilitate transmission of the third guided electromagnetic waves by the third launcher on the third segment of the transmission medium.
