PURPOSE:To improve the insertion loss and specific band width with reduced size, by using >=3 ferrite cores, providing a center conductor between layers and connecting them in series electrically. CONSTITUTION:Three sheets, one set of network center conductors 12a-12c and 12'a-12'c are inserted between two layers consisting of three ferrite cores 6a, 6b and 6c. One end the center conductors 12'a-12'c is grounded and other end is connected between one end of other center conductors 12a-12c and outside of the ferrite cores 6a-6c. Other end of the center conductors 12a-12c is used for the connection of an external circuit. Thus, the inductances consisting of the center conductors 12a-12c, 12'a-12'c are electrically in series connection, allowing to increase the total inductance. |
