摘要：
A multilayered frequency separator comprising a plurality of insulating layers, and having at least two notch circuits. The notch circuit is constituted by pattern electrodes formed on interfaces of each of the insulating layers which construct the multilayer structure, and comprises a capacitor component connected to an inductance component. The multilayered frequency separator is suitably used for branching the frequency bands for dual-band handy phone.
