Abstract
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 substrate. This leaves two lines unconnected at this layer. The third layer is a dielectric layer which has through-holes to: 1) each end of the unconnected lines of the bottom layer, 2) the unconnected ends of the outermost lines and, 3) the middle of the center line. The fourth layer of material is a conductive layer. The fourth layer is arranged as three parallel lines, each perpendicular to the lines of the second layer. The conductor lines of the fourth layer connect and extend through the holes of the dielectric layer to the lines of the second layer, forming the complete circuit.
