BALANCE-UNBALANCE CONVERTER

摘要

A balance-unbalance converter includes a low pass filter including a first inductor and a first capacitor and a high pass filter including a second inductor and a second capacitor. A via continuous portion of the first inductor penetrates a helix of a helical portion of the second inductor, and a via continuous portion of the second inductor penetrates a helix of a helical portion of the first inductor.

1. A balance-unbalance converter comprising:
a multilayer body including a plurality of insulating layers laminated in a lamination direction; an unbalanced terminal, a first balanced terminal, and a second balanced terminal on a surface of the multilayer body; a capacitor electrode between predetermined ones of the plurality of insulating layers of the multilayer body; a line electrode between predetermined ones of the plurality of insulating layers of the multilayer body; a via electrode that penetrates between both principal surfaces of a predetermined one of the insulating layers; a low pass filter connected between the unbalanced terminal and the first balanced terminal and including a first inductor and a first capacitor; and a high pass filter connected between the unbalanced terminal and the second balanced terminal and including a second inductor and a second capacitor; wherein the first inductor of the low pass filter has a structure such that a helical portion in which the via electrode and the line electrode are alternately connected and a via continuous portion in which a plurality of the via electrodes are connected to each other; the first capacitor of the low pass filter includes a plurality of the opposing capacitor electrodes; the second inductor of the high pass filter has a structure such that a helical portion in which the via electrode and the line electrode are alternately connected and a via continuous portion in which a plurality of the via electrodes are connected to each other; the second capacitor of the high pass filter includes a plurality of the opposing capacitor electrodes; the via continuous portion of the first inductor penetrates a helix of the helical portion of the second inductor; and the via continuous portion of the second inductor penetrates a helix of the helical portion of the first inductor.
