A Lange coupler device which includes a first layer which is a base substrate of a dielectric material such as alumina. Deposited on this substrate are second, third and fourth layers of the device. Each layer is made from a thick-film material. The second layer is a conductive layer, arranged in five parallel lines. One of the outermost lines is connected to the center line at one end of the substrate while the other outermost line is connected to the center line at the opposite end of the subs...
