摘要

在平面空腔中激发的功率/地噪声可以通过开孔耦合到相邻的平面空腔中。谐振腔的耦合噪声很大。本文在仿真和测量的基础上，提出了一种通过开孔降低耦合噪声的方法。我们证明了耦合噪声可以通过在适当的位置放置端口(器件)或仔细设计平面腔的尺寸来抑制。

Reduction of cavity-to-cavity power/ground noise coupling through plane cutout in multilayer PCBs

Power/ground noise excited in a plane cavity can be coupled to a neighboring plane cavity through a cutout. The coupled noise is substantial at the cavity resonance. The paper addresses a method of reducing the coupled noise through a cutout based on simulation and measurement. We demonstrated that the coupled noise can be suppressed by placing ports (devices) at the proper locations or designing the size of the plane cavity carefully.
