This report discloses the full FORTRAN IV program for an IBM 7094 digital computer for the automatic design of arbitrary TEM quadrature couplers and differential phase shifters. The design is completely general in the sense that any number of coupled quarter wavelength sections, any nominal coupling value or phase shift, and any design bandwidth of operation can be realized, although the user may specify any maximum coupling value in the design. This last degree of freedom in the specification to the machine, which is all- important in the physical realization of a theoretical design, is met by finding the proper number and types of tandem coupled junctions in the solution. This computer solution will be optimum. It will find the least ripple for the required bandwidth of operation for any input design complexity.
