摘要

提出了一种在两层印刷电路板上吸收和抑制共模噪声的新结构。通过引导CM噪声到一个电阻，它可以作为热量被吸收和消散。在测量中，CM的噪声吸收和抑制波段分别为2.19 ~ 3.02 GHz和1.78 ~ 3.11 GHz。最重要的是，通过单细胞结构实现了0.029 λg2的超紧凑尺寸。

A Wideband Single-Cell Unidirectional Absorption Common-Mode Filter with Pattern Ground Structure

A new configuration for common-mode (CM) noise absorption and suppression is proposed in a two-layer printed circuit board. By directing CM noise to a resistor, that can be absorbed and dissipated as heat. In measurement, broad CM noise absorption and suppression bands are achieved from 2.19 – 3.02 GHz and 1.78 – 3.11 GHz, respectively. Most of all, an ultra-compact size of 0.029 λg2 is achieved by a single-cell structure.
