研制了一种新型多层共模滤波器。它包括一个内部耦合曲折的导体线之间的顶部和底部的镍锌铁氧体基板，聚酰亚胺介电夹层，和外表面接地层。由于Ni-Zn铁氧体基片同时具有磁性和介电性能，滤波器的功能类似于耦合分布常数线。制作的滤波器表现出33 dB的共模信号衰减在3 GHz左右。
A new multilayered common-mode filter was fabricated. It consisted of an inner coupled meander conductor line between top and bottom Ni-Zn ferrite substrates, polyimide dielectric interlayers, and outer surface ground planes. Since the Ni-Zn ferrite substrate had both magnetic and dielectric properties, the filter functioned as a coupled distributed constant line. The fabricated filter exhibited common-mode signal decay of 33 dB at around 3 GHz.
