<p>The purpose of the present invention is to ensure relatively significant isolation in a ferrite absorption type isolator. A ferrite absorption type isolator equipped with: ferrite (10); a connected conductor (15) which is provided on the ferrite (10) and has a first opening (P1), a second opening (P2), a third opening (P3), and a fourth opening (P4); and permanent magnets (20) which apply a direct-current magnetic field to the ferrite (10). The connected conductor (15) comprises a main line which is arranged between the first opening (P1) and the second opening (P2) and two sub-lines which are respectively branched from the main line and reach the third opening (P3) and the fourth opening (P4). Two of the four openings are used as input and output ports, reactance components (C1, C2 or L1, L2) are connected to the remaining two openings, and the reactance components are connected to the ground.</p> |
