 note = {application/pdf, A（3,3）-port hybrid circuit is considered as a kind of（m, n）-port hybrid circuit. It can be attained by making its configuration similar to that of the Rat-Race circuit. Although its output power ratio is not unity at f_0，which is the center frequency of transmission，other hybrid characteristics are perfect at f_0. The method of improving the hybrid characteristics of the Rat-Race circuit in the neighbourhood of f_0 is also effective in this case， and the results of theoretical calculations of the hybrid characteristics are shown.},
