Abstract
Aspects of the subject disclosure may include, for example, a guided wave launcher generates, in response to an output RF signal, a guided electromagnetic wave along a surface of a transmission medium, wherein the guided electromagnetic wave propagates along the surface of the transmission medium without requiring an electrical return path, and wherein the guided electromagnetic wave has a non-optical carrier frequency. A mismatch probe generates a mismatch signal based on the output RF signal, wherein the mismatch signal indicates an impedance mismatch of the guided wave launcher. A controller generates one or more control signals in response to the mismatch signal, wherein the one or more control signals adjust one or more adjustable circuit elements of an impedance matching circuit, wherein adjustment of the one or more adjustable circuit elements facilitates reducing the impedance mismatch of the guided wave launcher. Other embodiments are disclosed.
