Abstract: A distributed-line directional coupler including: a first conductive line between first and second ports intended to convey a signal to be transmitted; and a second conductive line, coupled to the first one, between third and fourth ports, the second line being interrupted approximately at its middle, the two intermediary ends being connected to attenuators.
