摘要

An ultra-wideband filter is designed for common mode noise (CMN) suppression in high-speed differential signaling. It is realized by etching Φ-shaped pattern on the ground plane beneath the center of differential lines. The equivalent circuit model and surface current distribution are given to explain the working principle of the filter. A test sample is designed and fabricated with standard PCB technology. The measured results show that the fractional bandwidth of the presented CMN filter is 106% with a noise suppression level of 20 dB, while good transmission characteristic is maintained for the differential signals.
