PURPOSE:To make a strip line circulator small-size to reduce insertion loss by making the outside diameter of a permanent magnet fitted to the earth conductor larger than that of a permanent magnet fitted to the center conductor in respect to the strip line circulator used in a micro wave band. CONSTITUTION:Ferrite magnet 1a is fixed to the surface of ferrite core 2 through center conductor (strip line) 3 by adhesive, etc., and ferrite magnet 6 is fixed to the reverse face of ferrite core 2 through earth conductor 4 by adhesive, etc., and outside diameter D1 of ferrite magnet 1a is made equal to or larger than outside diameter D2 of ferrite magnet 6. |
