Abstract: An electric circuit includes a compensation circuit. The compensation circuit includes at least one directional coupler with an adjustable coupling factor. The compensation circuit is coupled between a first signal path and a second signal path of the electric circuit via the at least one directional coupler. Furthermore, the electric circuit includes a detector circuit coupled at least to the second signal path. The detector circuit is configured to detect an interfering signal portion of a signal of the first signal path in the second signal path. Furthermore, the electric circuit includes a control circuit. The control circuit is configured to adjust a transfer characteristic of the compensation circuit based on the detected interfering signal portion. Adjusting the transfer characteristic includes adjusting the coupling factor of the at least one directional coupler.
