7 Conclusion

  The HA5WH network takes advantage of cyclic symmetry to give simple design equations, and excellent sideband suppression with ideal components. If the cyclic symmetry is maintained, the network is not very sensitive to component tolerances. This means that the components in each of the network sections should be carefully matched. Breaking the cyclic symmetry by using unmatched components can drastically effect the performance of the network.

I have given a set of formulas and Fortran programs to design the optimum ideal networks, and to analyze both the ideal and nonideal cases. Analyses other than the cases that I have described here can be easily done with these methods and codes.
