Abstract
A directional coupler having a first structure with distributed lines having a first conductive line intended to convey a main signal between two end terminals and having a second conductive line, coupled to the first one, intended to convey a secondary signal proportional to the main signal; and a second structure with local elements including, between a first terminal of the coupler intended to extract the secondary signal and a first end of the second line, two attenuators in series between which is interposed a low-pass filter and, between a second terminal of the coupler and the second end of the second line, at least one attenuator.
