Abstract
A high-frequency coupler for extracting a secondary signal representative of a main signal carried by a conductive line, including two series-coupled, respectively high-pass and low-pass, filters, and the input of which is intended to be connected to said line while its output is intended to provide the secondary signal, the filters being sized so that the sum of their respective attenuations is substantially constant over the coupler passband, and so that their respective cut-off frequencies are in said passband.
