    • In a circuit module in which a plurality of non-reciprocal circuit elements, each of which does not have a yoke, are mounted, the occurrence of magnetic coupling between the non-reciprocal circuit elements is significantly reduced and prevented. Core isolators are not arranged such that, in a state in which the direction of magnetic flux and the direction of magnetic flux are the same, the core isolators are aligned in the direction of the magnetic flux. Specifically, the core isolators generate the magnetic flux from left to right. The core isolators are aligned so as to be inclined relative to the magnetic flux. Thus, extension of the magnetic flux through the core isolator in a state of being directed in the same direction as that of the magnetic flux is significantly reduced and prevented.
    • 在其中安装了各自不具有磁轭的多个不可逆电路元件的电路模块中,显着地减少并防止了在不可逆电路元件之间发生磁耦合。 核心隔离器不被布置成使得在磁通方向和磁通方向相同的状态下,芯隔离器在磁通量的方向上排列。 具体来说,核心隔离器从左到右产生磁通量。 核心隔离器被排列成相对于磁通量倾斜。 因此,以与磁通相同的方向指向的状态,通过芯隔离器的磁通量的扩展被显着地减少并被防止。
