Abstract :
A novel transmission-line-type eight-port hybrid is proposed and investigated theoretically and experimentally. A bandwidth comparable with that of a branch-line 3 dB hybrid is obtained for moderate values of characteristic admittances of line sections. This circuit is useful for applications to a comparator circuit in a four-port monopulse radar system and a four-way power combiner/divider with four input/output arms isolated from one another.<>
