ABSTRACT:
A termination for absorbing electromagnetic energy provided by a transmission line and for transferring any resulting heat to a heat sink. The termination comprises a housing in communication with the transmission line for receiving the electromagnetic energy, and in communication with the heat sink for transferring the resulting heat thereto. The termination also includes a conductor disposed within the housing and cooperating with the housing for providing an internal transmission line structure for confining and guiding the electromagnetic energy within the termination. The termination also includes an absorber comprising a lossy dielectric. The absorber is disposed within the housing and is in communication with the internal transmission line for receiving the electromagnetic energy and absorbing the electromagnetic energy in accordance to an absorption profile of the termination. The absorber converts the absorbed energy into heat and is in communication with the housing for transferring the heat thereto.
