    摘要： A directional coupler including at least two coupled lines and at least three ports is disclosed. A first coupled line of the at least two coupled lines includes at least two ports such as an input port and an output port. A second coupled line of the at least two coupled lines includes a forward path and a backward path that are joined together at a third port to form a loop. To achieve a constant coupling attenuation over a broad frequency band and to minimize dimensions, the second coupled line includes a higher line impedance than the first coupled line, at least two times higher, and a coupling resistor is connected in series either in the forward path or in the backward path. In a multichannel power splitter, directional couplers are arranged in series with one another.
