PURPOSE:To improve isolation characteristics between branch terminals by adding open-tip lines to both branch strip lines of a branching circuit consisting of the microstrip lines. CONSTITUTION:Open-tip lines 31 and 32 made of strip lines are added to part of branch lines 3 and 4. Consequently, even when this is used for a micro-wave having a relatively high frequency, input impedance from an input terminal 5 is excellent and isolation characteristics between branch terminals 6 and 7 are improved, thus obtaining a hybrid circuit which has distribution characteristics. |
