Title: NONRECIPROCAL CIRCUIT
Abstract:
The present invention comprises a ferrite substrate (5) provided so as to be bonded to a center conductor (3a) of a dielectric substrate (3), and a high-permeability member (6) provided so as to be bonded to the ferrite substrate (5). Via holes (7a-1 to 7a-3, 7b-1 to 7b-3, 7c-1 to 7c-3) and conductors (8a-1 to 8a-3, 8b-1 to 8b-3) electrically connect the center conductor (3a) and input-output terminals (3c-1 to 3c-3), and a via hole (9) electrically connects a ground conductor (3b) and the high-permeability member (6).
